We use forcewake to prevent the SoC from actually entering
PC8 while performing the PC8 disable sequence. Hide that
behind a new parent interface to eliminate the naked
forcewake/uncore usage from the display power code.
v2: Mark the interface optional and warn if
someone calls it when not provided (Jani)
Include the header to make sure the extern
declaration matches the definition (Jani)
v3: Rebase due to shuffling

Aligning with the parent interface struct definitions, also group and
sort the parent interface wrappers to improve clarity on where to add
new stuff.

Move the panic handling to the display parent interface, making display
more independent of i915 and xe driver implementations.

Whether AuxCCS can be properly supported depends on the support both from
the display side and non-display side of the driver.
Let us therefore allow for the non-display part to be queried via the
display parent interface.
The new interface replaces the HAS_AUX_CCS macro and we also remove the
FIXME from skl_universal_plane_create since now the xe will not advertise
the AuxCCS caps to start with so they do not need to be removed after
enumeration.
Also, by removing this build specific FIXME we come a step closer to fully
de-coupling display and non-display.
The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is still
required for determining the need for PLANE_AUX_DIST programming.

Call the stolen memory interface through the display parent interface.
This makes xe compat gem/i915_gem_stolen.h redundant, and it can be
removed.
v2: Rebase, convert one more call that appeared

The HDCP GSC implementation is different for both i915 and xe. Add it to
the display parent interface, and call the hooks via the parent

Add an irq parent driver interface for the .enabled and .synchronize
calls. This lets us drop the dependency on i915_drv.h and i915_irq.h in
multiple places, and subsequently remove the compat i915_irq.h and
i915_irq.c files along with the display/ext directory from xe
altogether.
Introduce new intel_parent.[ch] as the wrapper layer to chase the
function pointers and convert between generic and more specific display
types.
v2: Keep static wrappers in intel_display_irq.c (Ville)
v3: Full blown wrappers in intel_parent.[ch] (Ville)
