[PATCH] wifi: ath11k: support fetching mac address from nvmem

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

Many embedded devices with ath11k wifi chips store their mac address in
nvmem partitions. Currently, the ath11k driver supports getting the
mac address from the 'mac-address', 'local-mac-address', and 'address'
device tree properties only. As such, add support for obtaining the mac
address from nvmem if defined in a 'mac-address' cell by replacing the
call to device_get_mac_address by of_get_mac_address which does exactly
the same as the former but tries to get it from nvmem if it is not set
by above mentioned DT properties,

Tested-on: IPQ5018, QCN6122, and QCN9074
