[PATCHv3 ath-next] wifi: ath10k: add nvmem support for mac address

[Rosen Penev <rosenp@gmail.com>]

device_get_mac_address is a generic way to get the MAC address which
lacks NVMEM support, which tends to be used on embedded platforms.

of_get_mac_address has NVMEM support and handles most of what
device_get_mac_address does. The only thing missing is ACPI which is not
used to store MAC addresses for ath10k chips.

 v2: keep device_get_mac_address and use of_get_mac_address_nvmem
 v3: back to of_get_mac_address
