qcacmn: Add functionality to send bridge MAC to firmware

Add functions to send bridge MAC programmed from user
space to firmware.This change is part of a workaround
to fix an looping issue which resulted in wrongly adding
bridge's own MAC address to fw WDS table.Send MAC address
to target to avoid adding our own bridge address to fw
WDS table as part of source port learning.
