wl12xx: add testmode operation to read the BD_ADDR from Fuse ROM
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.
