[PULL] drm-intel-gt-next

[Joonas Lahtinen <joonas.lahtinen@linux.intel.com>]

Hi Dave & Daniel,

Here is the first drm-intel-gt-next feature PR towards v5.18.

For DG2 adds subplatform G12, missing workarounds and fixes GuC
loading on ARM64. C0/D0 stepping info added for RPL-S.

For uAPI enables support for simple parallel submission with
execlists which was previously enabled only for GuC.

Further fixes for PMU metrics when GuC is enabled, better error
reporting for GuC loading failures. Fix for PXP unbind splat.
Updates to GuC version 69.0.3 with improvements to GT reset
scenarios.

The rest is mostly refactoring of the memory management code,
as highlights introduction of async unbinding/migration and
removal of short-term pinning in execbuf.

Then a few selftest and coding style fixes.

Regards, Joonas
