Add register definitions of the MIPI CCS 1.1 standard.

The CCS driver makes extended use of device's capability registers that
are dependent on CCS version. This involves having an in-memory data
structure for limit and capability information, creating that data
structure and accessing it.

The register definitions as well as the definitions of this data structure
are generated from a text file using a Perl script. Do the generation here
and so avoid making manual, error-prone changes to the several generated
files.

Also add ccs-os.h header that contains Linux headers to be included.
