Jonas Gorski d21a771346 MIPS: BCM63XX: Properly handle mac address octet overflow 
While calculating the mac address the pointer for the current octet was
never reset back to the least significant one after being decremented
because of an octet overflow. This resulted in the code continuing to
increment at the current octet, potentially generating duplicate or
invalid mac addresses.

As a second issue the pointer was allowed to advance up to the most
significant octet, modifying the OUI, and potentially changing the type
of mac address.

Rewrite the code so it resets the pointer to the least significant
in each outer loop step, and bails out when the least significant octet
of the OUI is reached.
