V4L/DVB (13088): cx25840: Convert chip/core family checks to static inline functions
Change logic to check for various chip or core families to inline functions.
Checks for specific chips should be made against the state->id field now. This
is in preparation for chip/core specific code for setting up PLLs for the
CX2388[578] family of cores, that all run with different crystal frequencies.
