From [1], I realized two other calls to dcn30 code are associated with
FPU operations and are not protected by DC_FP_* macros:
* dcn30_populate_dml_writeback_from_context()
* dcn30_set_mcif_arb_params()
So, since FPU-associated code is not fully isolated in dcn30, and
dcn3.1.x reuses them, let's wrap their calls properly.
Note: this patch complements the fix from [1].

Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.
The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.
Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

This reverts commit 863fa85e6a.
While we were testing DCN3.1 with a hub, we noticed that only one of 2
connected displays lights up when using some specific display
resolution. In summary, this was the setup:
1. Displays:
* Sharp LQ156M1JW26 (eDP): 1080@240
* BENQ SW320 (DP): 4k@60
* BENQ EX3203R (DP): 4k@60
2. Hub: Club3D CSV-7300
3. ASIC: DCN3.1
After bisecting this issue, we figured out the commit mentioned above
introduced this issue. We are investigating why this patch introduced
this regression, but we need to revert it for now.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c
In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:
out.rgb = plane_alpha * fg.rgb +
(1 - (plane_alpha * fg.alpha)) * bg.rgb
Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).
With this change, alpha property stops to be ignored. It also addresses
