Some recent Intel dGfx platforms allow media IP to work at a different
frequency from the base GT. This patch series exposes sysfs controls for
this functionality in the new per-gt sysfs. Some enhancements and fixes to
previous per-gt functionality are also included to complete the new
functionality:
* Patches 1 and 2 implement basic sysfs controls for media freq
* Patch 3 extends previous pcode functions for multiple gt's
* Patch 4 inits pcode on different gt's
* Patch 5 adds a couple of pcode helpers
* Patch 6 uses the new pcode functions to retrieve media RP0/RPn freq
* Patch 7 fixes memory leaks in the previous per-gt sysfs implementation
  and some code refactoring

IGT tests for this new functionality have also been posted at:

Test-with: 20220513011500.73460-1-ashutosh.dixit@intel.com

v2: Fixed commit author on patches 5 and 6 (Rodrigo)
    Added new patch 4
v3: Expose pcode functions in terms of uncore rather than gt (Jani/Rodrigo)
v4: Retain previous pcode function names to eliminate
    needless #defines (Rodrigo)
v5: Add new patch 4 and remove last two patches in the v4 series which will
    be submitted later. Other mostly minor fixes from code review
v6: Identical to v5, only update "Test-with:" since CI did not pick up
    previous "Test-with:" probably because it was old
v7: Rebase remaining patches after patches 1, 3 and 5 have been merged
