brcmfmac: check all combinations when setting wiphy's addresses

Browse Source 
Broadcom is working on better reflection of interface combinations. With
upcoming patches we may have 1st combination supporting less interfaces
than others.
To don't run out of addresses check all combinations to find the one
with the greatest max_interfaces value.
