[PATCH v4 5/6] media: ccs: Better separate CCS static data access

[Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>]

Separate CCS static data read-only register access in ccs-reg-access.c by
naming them differently.

The code in this file generally deals with reading and writing registers
where as static data (when it comes to ccs_static_data_read_ro_reg())
contains the read-only register values but no hardware registers are
accessed in that case.
