Subject: [PATCH 0/2] Some small preparations around CAMSS D-PHY / C-PHY
 support

Since the hardware blocks on the SoCs generally support both D-PHY and
C-PHY standards for camera, but the camss driver currently is only
supporting D-PHY, do some preparations in order to add C-PHY support at
some point.

Make the dt bindings explicit that the hardware supports both (except
for MSM8916) but also add a check to the driver that errors out in case
a dt tries to use C-PHY since that's not supported yet.
