drm/xe/xe3: Apply Wa_16029380221 to media
Apply Wa_16029380221 to Xe3p_LPM.
The Xe3p_LPM media page walker is hard-wired NonCoherent and cannot
observe CPU:WB cached page table data. Force page tables to CPU:WC
by clearing has_cached_pt when MEDIA_VERSION(3500) is detected.
v2: Simplify code comment to avoid duplicating information
already present in xe_wa_oob.rules. (Gustavo)
