drm/xe/xelp: L3 recommended hashing mask
According to the i915 codebase xe missed to set the recommended
performance tuning for L3 hashing which is applicable to all legacy XeLP
platforms. Lets add it.
v2:
* Rename prefixes to XELP_.
* Tweak version end point.
v3:
* Add bspec tag.
* Tweak version range.
v4:
* Move from LRC to engine tunings list.
v5:
* Drop L3 Cache Control comment.
Bspec: 31870
