Bluetooth: btbcm: Move request/release_firmware()
Move request/release_firmware() out of btbcm_patchram(). This allows a better error management, if request_firmware() returns an error then the controller will be used without firmware loading and 0 is returned. This will imply to change btbcm_patchram() to accept a firmware instead of firmware name.
