Add in CAMCC for sc8280xp. The sc8280xp Camera Clock Controller looks
similar to most of the sdmX, smX and now scX controllers.

clock-names is now redundant :)

BTW.

Looking at the block diagram for the Camera, I see why Cam_CC_AHB is included in this list. Its not called out as a dependency in the clock tree but when you look at the block diagram you can see it gates the AHB bus to the CAM_CC block.
Yep, that's why using is as pm_clk for the clock controller makes sense
