Tomasz Maciej Nowak 946e42ed89 mac80211: brcmfmac: allow setting MAC from NVMEM cells
The MAC can be stored in OTP memory or in flash memory, currently the
driver could read it only from OTP. Backport the patch allowing setting
the MAC address from flash. Some modules have the OTP programmed but
the ODM/OEM decided to overwrite it with value stored in flash.

Subject: [PATCH] brcmfmac: add in-driver tables with country codes

This adds early support for changing region. Ideally this data should
be stored in DT as all these mappings are devices specific.
