drm/xe: Define and use MCR version of COMMON_SLICE_CHICKEN4

The register COMMON_SLICE_CHICKEN4 is a MCR register on both Xe2 and
Xe3. Let's make sure to define a MCR version of it and use it for the
relevant IP versions.

Use XEHP_ as prefix for the register name, since it is MCR as of Xe_HP.

v2:
  - Also change for one entry in lrc_tunnings, which was caught by
    manual testing and add corresponging Fixes tag in commit message.
