wl1271: Remove device MAC-address randomization

This patch removes the MAC address randomization from the driver. This removes
a nasty Nokia-OUI dependency from the driver.

With this patch, unless an address is explicitly configured to the driver
by the user, only a zero address will be configured, and the driver will be
unable to start.
