drm/xe: Create page reclaim list on unbind

Page reclaim list (PRL) is preparation work for the page reclaim feature.
The PRL is firstly owned by pt_update_ops and all other page reclaim
operations will point back to this PRL. PRL generates its entries during
the unbind page walker, updating the PRL.

This PRL is restricted to a 4K page, so 512 page entries at most.

v2:
- Removed unused function. (Shuicheng)
- Compacted warning checking, update commit message,
spelling, etc. (Shuicheng, Matthew B)
- Fix kernel docs
- Moved PRL max entries overflow handling out from
generate_reclaim_entry to caller (Shuicheng)
- Add xe_page_reclaim_list_init for clarity. (Matthew B)
- Modify xe_guc_page_reclaim_entry to use macros
for greater flexbility. (Matthew B)
- Add fallback for PTE outside of page reclaim supported
4K, 64K, 2M pages (Matthew B)
- Invalidate PRL for early abort page walk.
- Removed page reclaim related variables from tlb fence
(Matthew Brost)
- Remove error handling in *alloc_entries failure. (Matthew B)

v3:
- Fix NULL pointer dereference check.
- Modify reclaim_entry to QW and bitfields accordingly. (Matthew B)
- Add vm_dbg prints for PRL generation and invalidation. (Matthew B)

v4:
- s/GENMASK/GENMASK_ULL && s/BIT/BIT_ULL (CI)

v5:
- Addition of xe_page_reclaim_list_is_new() to avoid continuous
allocation of PRL if consecutive VMAs cause a PRL invalidation.
- Add xe_page_reclaim_list_valid() helpers for clarity. (Matthew B)
- Move xe_page_reclaim_list_entries_put in
xe_page_reclaim_list_invalidate.

Merge drm/drm-next into drm-xe-next

Backmerging to bring in a needed dependency for the Xe VFIO
driver variant. This should ideally have been done before we
commited that, so we now have a small window in drm-xe-next
where that driver doesn't compile.

drm/xe/pf: Add TLB invalidation support for MERT

Add support for triggering and handling MERT TLB invalidation. After
LMTT updates, the MERT TLB invalidation is initiated to ensure memory
translations remain coherent.

Completion of the invalidation is signaled via MERT interrupt (bit 13 in
the GFX master interrupt register). Detect and handle this interrupt to
properly synchronize the invalidation flow.
