In case of MCU with multiple firmware slots support, change of active
slot requires reset. This obviously results in MCU entering the serial
recovery mode in bootloader, with 5 sec timeout, which in case of UART
based MCUs isn't automatically detected and handled in the same way as
USB based devices (hotplug).
Starting host side support script when the MCU is waiting for MCUmgr
commands during recovery is wrong. This fixes the problem by requesting
UART based MCU to boot the firmware after active slot change followed by
reset. While at it, change also how single slot type MCUs are handled
during upgrade (always request reset after the upgrade).

This includes shell script for host side support of the 'hci_uart' MCU
firmware type. The script calls 'btattach' with matching tty interface
and baud rate as arguments, resulting in new Bluetooth HCI controller
registration in the system. Both UART and USB interfaces are supported.

This adds support for executing a host side support script per firmware
type (in our case, full MCU firmware name is a combination of two terms:
'version__type', e.g. 'zephyr-v3.3.x__hci_uart') which currently runs on
the MCU. Additionally, support for calling the init script with 'stop'
argument is included.
The host side support scripts will be placed in '/etc/mcu.d/' and should
have executable flag set and be named after the firmware type, with 'sh'
extension (e.g. 'hci_uart.sh'). This solution assumes also that PID of a
running, related service will be stored in '/var/run/mcu.SN.pid' where
'SN' is the associated MCU serial number.

In case of some of the MCU firmware types, additional setup on the host
side is required before the target application can be used. Example of
such a requirement is a BLE HCI controller on UART bus (firmware type:
'hci_uart') which, before can be registered in system, needs to be
attached to Bluetooth stack (with e.g. 'btattach').
This includes code for generating hidden packages under 'mcu-firmware'
with all the files required for host side support (stored in directory
with the same name as firmware type, under local 'files' directory),
for a selected MCU firmware. For example, below tree:
./feeds/mcu/mcu-firmware/files/hci_uart/etc/...
would result in creation of new package 'zephyr-hci_uart-host-support',
included in dependencies lists for all MCU firmware versions of the
'hci_uart' type, with everything from '.../files/hci_uart/'.

In case of some types of MCU firmware, additional tools, daemons, kernel
drivers, etc. are required on the host side. For example, for Bluetooth
HCI controller, at least kernel module and BlueZ should be included.
This adds a simple recipe which generates dependencies list per firmware
type/name and for existing 'hci_usb' and 'hci_uart', selects 3 packages:
'bluez-daemon', 'kmod-bluetooth' and 'kmod-crypto-user'.
Kernel crypto interface in user space has to be also included because
the BlueZ isn't able to create static address for LE-only controller
without it, which results in no registration of new BT interface:
bluetoothd[668]: src/adapter.c:get_static_addr() Failed to open crypto
bluetoothd[668]: No Bluetooth address for index 0

The new 'mcu-firmware' package will provide binary firmware dedicated
for MCU embedded on Wi-Fi boards (and also standalone, e.g. USB based),
supported by the OpenWrt/OpenWiFi projects. Currently, only Zephyr RTOS
based sample firmware ('BLE HCI controller' and 'hello world') files are
provided, for Wi-Fi boards and one standalone development module, listed
below:
- CIG WF-196 (Nordic nRF52833, UART bus)
- EdgeCore EAP102 (Nordic nRF52840, USB bus)
- Nordic nRF52840 Dongle (Nordic nRF52840, USB bus)
Different firmware types planned in future include Nordic's nRF Connect
SDK, OpenThread and others.
The Zephyr based firmware comes from a custom fork available in GitLab:
'https://gitlab.com/pepe2k/zephyr' (firmware in this package were built
from a v3.3.0 release based branch 'zephyr-v3.3.x__mcu-on-wifi-boards').
MCU firmware from this package is compatible only with OpenWrt/OpenWiFi
generic MCU support stack which, among others, assumes availability of
compatible bootloader (MCUboot is currently the only one supported) and
e.g. multiple firmware slots. MCUboot fork development takes part in git
repository hosted in GitLab: 'https://gitlab.com/pepe2k/mcuboot/'.

This introduces new package 'mcu' which is a collection of shell based
scripts used as glue code for generic MCU configuration and management.
The scripts are responsible for communicating with embedded MCU running
compatible MCUboot bootloader version over MCUmgr/SMP protocol.
The communication is realized based on usage of the introduced earlier
dedicated CLI tool called 'umcumgr.
The most important function of this package is a simple MCU's firmware
management (checking firmware available in the MCU's internal flash,
uploading new and selecting active on multi-firmware slot capable MCU).
This solution requires MCU running modified version of MCUboot,
available in GitLab: https://gitlab.com/pepe2k/mcuboot

This change focuses on the I/O related cleanups for the CIG WF-196 DTS
file. Most of the removed definitions come from QCA reference files and
should have been adjusted for a custom board. List of changes:
1. Drop 'btcoex' pinctrl mux define
WF-196 includes nRF52833 MCU which doesn't have dedicated PTA coex
hardware interface (see [1] for software based solution in Nordic's
nRF Connect SDK). Based on the real hardware research, defined pins
from 'btcoex' mux aren't routed to nRF52833 MCU.
2. Drop 'spi_3' pinctrl mux define
Defined label isn't used as reference in any other node and defined
GPIOs most likely aren't used as well.
3. Drop GPIO 46 and 47 from hsuart pinctrl mux define
It turned out that only UART TX and RX lines are routed between the
main SOC (IPQ8072A) and the MCU (nRF52833).
While at it, fix also some broken indentation and redundant new lines.
