msm: camera: add support for bus overflow recovery

When bus overflow is detected, system can enter bad state. So we
halt, reset and restart the AXI Bus Bridge, CAMIF and ISPIF INTF
in order to recover.
On overflow detection, kernel halts the AXI Bus Bridge and sends ERROR
message to user spacce and wait for it to trigger reset and restart.
