drm/xe/nvlp: Implement Wa_14026539277

Browse source

Implement the KMD part of Wa_14026539277, which applies to NVL-P A0.
The KMD implementation is just one component of the workaround, which
also depends on Pcode to implement its part in order to be complete.

v2:
  - Add FUNC(xe_rtp_match_not_sriov_vf) to skip applying the workaround
    to SRIOV VFs. (Matt)
v3:
  - Make Wa_14026539277 a device workaround instead of a GT workaround.
    (Matt)
v4:
  - Drop FUNC(xe_rtp_match_not_sriov_vf) and use a direct check with
    IS_SRIOV_VF() in the workaround implementation. (Matt)
