qca-nss-drv: add option to configure NSS memory profile

Similar to how memory profile is assignable for ath11k, introduce a
config option to set NSS memory profile. Default was always set to
512MB in upstream for ipq807x even though the platform is available in
256MB/512MB/1GB.

This option primarily limits the default number of offloaded
connections, and for low memory profile, empty buffer pool size

Default number of connections for each IPv4 and IPv6
* NSS_MEM_PROFILE_HIGH    4096
* NSS_MEM_PROFILE_MEDIUM  2048
* NSS_MEM_PROFILE_LOW     512

MAX Connection shared between IPv4 and IPv6
* NSS_MEM_PROFILE_HIGH    8192
* NSS_MEM_PROFILE_MEDIUM  4096
* NSS_MEM_PROFILE_LOW     1024
