intel_pch_init_clock_gating() and switch the corresponding
CFL/CML caller to the display-specific code.

Add a new function in the display code to help initialize clock-gating
without reading display PCH registers directly from non-display code.
This adds a mini-framework to deal with display-specific PCH registers
and uses it for IBX as a start.

Add intel_display_utils.c for display utilities that need more than a
header.
Start off with intel_display_run_as_guest(). The implementation is
intentional duplication of the i915_utils.h i915_run_as_guest(), with
the idea that it's small enough to not matter.

We no longer need i915_drv.h in intel_pch.c, and we no longer need
intel_pch.h universally.
With intel_pch.h being included from intel_display_core.h, it's still
included pretty much everywhere, but there's no need to include it
explicitly from i915_drv.h or xe_device_types.h.

Now that intel_pch lives under display, let's begin its
conversion towards struct intel_display.
Move the pch_type to inside intel_display and convert the
callers.
While doing it, sort intel_display_core.h include list
alphabetically.

The only usage of the "PCH" infra is to detect which South Display
Engine we should be using. Move it under display so we can convert
all its callers towards intel_display struct later.
No functional or code change.
