[PATCH] drm/xe/tests: Add legacy IP descriptors to param generators

[Michal Wajdeczko]

Recently introduced kunit parameter generators where based on
the existing arrays which have only GDMID-bsaed IP and didn't
take into account legacy IP definitions from pre-GMDID era.

Add test only arrays with legacy IPs (as those will not change)
and extend param generators to start iterating over them.
