From: Matthew Brost @ 2023-12-14  0:08 UTC (permalink / raw)
  To: intel-xe; +Cc: Francois Dugast, Rodrigo Vivi

Remove concept of async vs sync VM bind queues, rather make all binds
async. As part of this clean up add drm_xe_syncs structure to
encapsulate all parts of syncs. This structure is shared between the
exec and bind IOCTLs. The structure has extra bits for a path to support
syncs IOCTLs in the future.

v2: Send correct version
