Add support of getting factory BDADDR from Controller's non-volatile memory(2/2)
When factory Bluetooth device address is stored in the BT Controller's
non-volatile memory (e.g. BCM4330 OTP memory) instead of devices's file system,
the BDADDR will be retrieved from the Controller while enabling Bluedroid core
stack.
Introduce USE_CONTROLLER_BDADDR preprocessor directive in the vendor lib.
After patchram download, check whether the BT Controller has a non-zero's BDADDR
stored in its non-volatile memory. If not, write BTIF's init BDADDR to the
Controller.
