drm/i915: refactor register fw read/write macros for recent GENs
The only difference for the more recent of those macros is the version
of the *_reg_<read/write>_fw_domains function. Passing the function
prefix in allows us to re-use the same macro to generate functions for
different GENs and will make it easier to add new accessors in the future
