Some dGfx pcode commands take additional sub-commands and parameters. Add a
couple of helpers to help formatting these commands to improve code
readability.
v2: Fixed commit author (Rodrigo)
v3: Function rename and convert to new uncore interface for pcode functions
Remove unnecessary #define's (Andi)
v4: Another function rename

drm/i915/pcode: Extend pcode functions for multiple gt's2022-05-20T08:11:27+00:00Ashutosh Dixitashutosh.dixit@intel.com2022-05-19T08:57:31+00:00urn:sha1:ee421bb4cb9535f44015634baad833dcc98c9062
Each gt contains an independent instance of pcode. Extend pcode functions
to interface with pcode on different gt's. To avoid creating dependency of
display functionality on intel_gt, pcode function interfaces are exposed in
terms of uncore rather than intel_gt. Callers have been converted to pass
in the appropritate (i915 or intel_gt) uncore to the pcode functions.
v2: Expose pcode functions in terms of uncore rather than gt (Jani/Rodrigo)
v3: Retain previous function names to eliminate needless #defines (Rodrigo)
v4: Move out i915_pcode_init() to a separate patch (Tvrtko)
Remove duplicated drm_err/drm_dbg from intel_pcode_init() (Tvrtko)

Prefer acronym-based naming to be in line with the rest of the driver.

drm/i915: split out intel_pcode.[ch] to separate file2021-10-14T15:04:17+00:00Jani Nikulajani.nikula@intel.com2021-10-14T10:28:57+00:00urn:sha1:4dd4375bc4ff217f0a4a931772400c987720fb65
The snb+ pcode mailbox code is not sideband, so split it out to a
separate file. As can be seen from the #include changes, very few places
use both sideband and pcode.
Code movement only.
