drm/xe/xe3p_lpg: Restrict UAPI to enable L2 flush optimization
When set, starting xe3p_lpg, the L2 flush optimization
feature will control whether L2 is in Persistent or
Transient mode through monitoring of media activity.
To enable L2 flush optimization include new feature flag
GUC_CTL_ENABLE_L2FLUSH_OPT for Novalake platforms when
media type is detected.
Tighten UAPI validation to restrict userptr, svm and
dmabuf mappings to be either 2WAY or XA+1WAY
V5(Thomas): logic correction
V4(MattA): Modify uapi doc and commit
V3(MattA): check valid op and pat_index value
V2(MattA): validate dma-buf bos and madvise pat-index
