Define and use the bitmasks for the x/y components
of the skl+ scaler window pos/size registers.
We stick to the full 16 bits mask here even though the
hardware limits are actually lower. The current (ADL)
hardware maximums are in fact: 14 bits for X size, 13 bits
for X pos, 13 bits for Y size/pos. Yes, that is correct,
X pos has less bits than the X size for some reason. But
that doesn't actually matter for now as we don't currently
even support such wide displays without the use of bigjoiner
(due to max plane width limit).
v2: Switch back to full 16bit masks since that's what
we use transcoder timign regs and PIPESRC as well

Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.
Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.
Also some places actually needed i915_irq.h too.

All the skl+ scaler registers are suitably confined to their own
cachelines so we don't need the uncore.lock to globally serialize
access to these registers. We actually already dropped some of this
in commit 14ad15296d ("drm/i915: Make skl+ universal plane
registers unlocked") as the plane scaler enabling/reconfiguration
became lockless. So let's complete that and remove the rest of
the locks from the scaler programming as well.

Add a table describing all the framebuffer modifiers used by i915 at one
place. This has the benefit of deduplicating the listing of supported
modifiers for each platform and checking the support of these modifiers
on a given plane. This also simplifies in a similar way getting some
attribute for a modifier, for instance checking if the modifier is a
CCS modifier type.
While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(),
as the cursor plane is registered with DRM core elsewhere.
v1: Unchanged.
v2:
- Keep the plane caps calculation in the plane code and pass an enum
with these caps to intel_fb_get_modifiers(). (Ville)
- Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as
well.
v3:
- s/.id/.modifier/ (Ville)
- Keep modifier_desc vs. plane_cap filter conditions consistent. (Ville)
- Drop redundant cursor plane check from skl_plane_has_rc_ccs(). (Ville)
- Use from, until display version fields in modifier_desc instead of a mask. (Jani)
- Unexport struct intel_modifier_desc, separate its decl and init. (Jani)
- Remove enum pipe, plane_id forward decls from intel_fb.h, which are
not needed after v2.
v4:
- Reuse IS_DISPLAY_VER() instead of open-coding it. (Jani)
- Preserve the current modifier order exposed to user space. (Ville)
v5: Use }, { on one line to seperate the descriptor array elements. (Jani)
