media: ti-vpe: cal: Rename cc_data to cal_camerarx

Browse Source 
The various data structures that describe the components of the camera
access layer (CAL) are named without much consistency. Start cleaning
this up by renaming the structure that describes the CAMERARX block,
cc_data, to cal_camerarx.
