[Intel-xe] [PATCH v15 00/10] xe_device_mem_access fixes and related bits

[Matthew Auld]

Main goal is to fix the races in xe_device_mem_access_get(). With that fixed we
can clean up some hacks and also start rolling it out to more places that need
it, including now asserting it around every mmio access. We also add lockdep
annotations for xe_device_mem_access_get() and fix the remaining lockdep
fallout.

v11 -> v12:
  - freq_rpe_show also needs the device to be awake
  - Improvements to the lockdep annotation patch
v13:
  - Simply the first patch (Anshuman), also drop three patches which can be
    dealt with later.
v14:
  - Missed also updating the fast CT path which recently changed.
v15:
  - Rebase on latest drm-xe-next.
