Add bindings, driver and dts to support the Camera Subsystem on the

These patches were tested on a Fairphone 4 smartphone with WIP sensor
drivers (Sony IMX576 and IMX582), the camera pipeline works properly as
far as I can tell.
Though when stopping the camera stream, the following clock warning
appears in dmesg. But it does not interfere with any functionality,
starting and stopping the stream works and debugcc is showing 426.4 MHz
while the clock is on, and 'off' while it's off.
Any suggestion how to fix this, is appreciated.

[ 5738.591009] gcc_camera_axi_clk status stuck at 'on'
FWIW 845 has .halt_check = BRANCH_VOTED here, which translates into
'dont check the state at disable', this one has BRANCH_HALT (i.e. spin
and keep checking the hw state)
+Taniya would BRANCH_VOTED be fitting for 6350 too? ^
The parent RCG of this clock is under NoC control, and seems like there is no
vote on the NoC while disabling this clock, hence this issue is observed.
The BRANCH_HALT_VOTED/BRANCH_HALT_SKIP should help, or if the NoC voting is
removed after the clock disable then also this issue should be resolved.
This is very useful, thanks for the insight!
Is any of these solutions specifically preferred from your side?
Konrad
From clock controllers side we can use the BRANCH_HALT_SKIP as this
covers both enable/disable scenarios. But this needs to be checked
further from consumer driver side as well to handle the NoC voting
properly.
Thanks,
Imran
