Stopping the CSI source before stopping the serializer
CSI port may make the serializer not respond.
Then all the next writes to the device will fail.
max96717 1-0040: Error writing reg 0x0308: -121
max96717 1-0040: Error writing reg 0x0006: -121
Fix that by stopping the CSI receiver first and then CSI source.
Seen on max96717f revision 4.

This driver handles the MAX96717 serializer in tunnel mode.
All incoming CSI traffic will be tunneled through the GMSL2
link.
The MAX96717 driver can handle MAX96717 and MAX96717F variants
with the same "maxim,max96717f" compatible.
