rockchip: add support for Ariaboard Photonicat2

Specification:
  SoC: RockChip RK3576
  Flash: 8 / 128 GB EMMC
  RAM: 4 / 16 GB LPDDR5
  Ethernet: 2x 10/100/1000 Mbps by RK3576 PHY
  LED: Power LED (G&R&Y) controlled by PMU
  WiFi: AIC8800U (Via USB HUB)
  WWAN: 1x M.2 B-Key (Via USB HUB)
  M.2: 1x E-Key && 1x M-key
  Button: Power direct connect to PMU
  USB: 1x USB3 (Via USB HUB)
  USB HUB: Genesys Logic HUB ( 05e3 : 0610 (usb2) / 0620(usb3) )
  HDMI: 1x HDMI
  LCD: 1x SPI LCD Display port
  Battery: 14000mAh @ 7.4v
  Power: USB-PD 12V 1.5A Max

To Flash the image to Emmc:
  Method A:
    Flash immortalwrt-rockchip-armv8-ariaboard_photonicat2-squashfs-sysupgrade.img.gz
    via Luci.

  Method B:
    A. Unzip the image and shutdown the system.
    B. Press the button three times briefly, then press and hold for 10
       seconds. （You can heard beeper sound differently from normal boot and pwr
       led blink yellow.）
    C. Connect the device to your pc via USB A --> A cable then flash the image
       via rkdeveloptool. (The manufacturer has provided the miniloader
       on https://dl.photonicat.com/images/photonicat2/RK3576_MiniLoaderAll.bin)

       sudo rkdeveloptool db RK3576_MiniLoaderAll.bin
       sudo rkdeveloptool wl 0 immortalwrt-rockchip-armv8-ariaboard_photonicat2-squashfs-sysupgrade.img
       sudo rkdeveloptool rd

There is a board specificate kernel driver that provide the ability to access
the minitor that connected to the PMU. The system can run without this
driver, so it would be added later as a kmod.
