media: mt9p031: Fix corrupted frame after restarting stream
[ Upstream commit 0961ba6dd211a4a52d1dd4c2d59be60ac2dc08c7 ]
To prevent corrupted frames after starting and stopping the sensor its
datasheet specifies a specific pause sequence to follow:
Stopping:
Set Pause_Restart Bit -> Set Restart Bit -> Set Chip_Enable Off
Restarting:
Set Chip_Enable On -> Clear Pause_Restart Bit
The Restart Bit is cleared automatically and must not be cleared
manually as this would cause undefined behavior.
