wl12xx: add testmode operation to read the BD_ADDR from Fuse ROM
Add a testmode command to retrieve the BD_ADDR that is stored in the Fuse ROM in newer PGs. In old PGs this operation is not supported. The caller can then derive the MAC addresses from it. Signed-off-by: Luciano Coelho <coelho@ti.com>
