SCDC is the Status and Control Data Channel for HDMI. Move the SCDC
helpers into display/ and split the header into files for core and
helpers. Update all affected drivers. No functional changes.
To avoid the proliferation of Kconfig options, SCDC is part of DRM's
support for HDMI. If necessary, a new option could make SCDC an
independent feature.

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.

We have an abstraction for the EDID base block read, yet duplicating the
retries and error handling for extension block reads. Introduce a more
generic EDID block read helper.
Switch to the helper piecemeal, starting with drm_edid_get_panel_id(),
which doesn't need or have access to the connector anyway.
The subtle change is switching from drm_edid_block_valid() to
edid_block_check(). We also status print once, not for every attempt.

Add edid_block_check() that only checks the EDID block validity, without

Rewrite drm_edid_block_valid() around it, keeping all the functionality
fairly closely the same, warts and all. Turns out it's incredibly
complicated for a function you'd expect to be simple, with all the
fixing and printing and special casing. (Maybe we'll want to simplify it

The invalid EDID block filtering uses the number of valid EDID
extensions instead of all EDID extensions for looping the extensions in
the copy. This is fine, by coincidence, if all the invalid blocks are at
the end of the EDID. However, it's completely broken if there are
invalid extensions in the middle; the invalid blocks are included and
valid blocks are excluded.
Fix it by modifying the base block after, not before, the copy.

With this, the remaining non-const parts are the ones that actually
modify the EDID, for example to fix corrupt EDID.

Use struct detailed_timing member access instead of direct offsets to
avoid casting.
Use BUILD_BUG_ON() for sanity check.
