[PATCH v3 00/10] Crescent Island PMT support

["Michael J. Ruhl" <michael.j.ruhl@intel.com>]

The Crescent Island (CRI) GPU supports PMT via Xe driver
registration.

The CRI PMT MMIO mapping is shared for each PMT feature and it is
necessary to set an index register value to access the correct memory
space.

The PMT driver has a callback infrastructure to access data areas with
driver specific access. It is does not support the PMT control access.

CRI discovery/control spaces are part of the access window so a driver
callback is necessary to allow for the correct window to be exposed.

Add control path callback support to the PMT driver.

Add CRI PMT discovery information.

Update the Xe driver to support the CRI PMT access.

The crashlog access needs to be done with power enabled (telem is only
available when the device is powered).

Determine which access is requested, and do the appropriate power
request.

CRI FW is loaded at device power.  Support the late-binding API to
wait for FW readiness. (pending sysctl patch set implements the API).

v2:
  Address AI feedback:
  - add missing entry->cb check
  - address SRIOV VF concerns
  - use xe_pm_runtime_put instead of _get in error path

  Address review comments:
  - redo power/lock sequencing
  - support device hotplug events

v3:
  - cleanup power manangement flow
  - fixed an out of order power management locking issue
  - add a GUID caching mechanism, for GUID read
  - removed unused parameter (mmio)
