MIO (CSI) SubsystemControl- 0x03 indicates powered off state, 0x00
indicates powered on state. Driver will write this field to register field to request power
up or power down for the MIPI controller. Note the implementation does not actually
power gate, but will turn off the clock trunks and apply reset to MIO .
