btbcm: fix btbcm driver for Lockdown

Lockdown doesn't yet have/need a Bluetooth firmware patch file:

Regardless, btbcm_set_bdaddr_base() needs to be called, so that
BD_ADDR of the Broadcom Bluetooth controller is set correctly.

After the fix:
GTCFSJ1548E0109# hnvram -r MAC_ADDR_BT

GTCFSJ1548E0109# hciconfig -a
hci0:   Type: BR/EDR  Bus: USB
        BD Address: F4:F5:E8:01:91:8D
