As talked about in commit d2aacaf07395 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

The vc4_dummy_plane structure was introduced as a mean to add
mock-specific fields.
However, we never really used it and it's still strictly equivalent to
vc4_plane (which is in the same situation vs drm_plane), so we can
simply remove the vc4_dummy_plane structure and make the mock code
cleaner.

There has been some discussions recently about the infoframes sent by
drivers and if they were properly generated.
In parallel, there's been some interest in creating an infoframe-decode
tool similar to edid-decode.
Both would be much easier if we were to expose the infoframes programmed
in the hardware. It won't be perfect since we have no guarantee that
it's actually what goes through the wire, but it's the best we can do.

Infoframes in KMS is usually handled by a bunch of low-level helpers
that require quite some boilerplate for drivers. This leads to
discrepancies with how drivers generate them, and which are actually
sent.
Now that we have everything needed to generate them in the HDMI
connector state, we can generate them in our common logic so that
drivers can simply reuse what we precomputed.

The i915 driver has a property to force the RGB range of an HDMI output.
The vc4 driver then implemented the same property with the same
semantics. KWin has support for it, and a PR for mutter is also there to
support it.
Both drivers implementing the same property with the same semantics,
plus the userspace having support for it, is proof enough that it's
pretty much a de-facto standard now and we can provide helpers for it.
Let's plumb it into the newly created HDMI connector.

Most of the HDMI controllers have an upper TMDS character rate limit
they can't exceed. On "embedded"-grade display controllers, it will
typically be lower than what high-grade monitors can provide these days,
so drivers will filter the TMDS character rate based on the controller
capabilities.
To make that easier to handle for drivers, let's provide an optional
hook to be implemented by drivers so they can tell the HDMI controller
helpers if a given TMDS character rate is reachable for them or not.
This will then be useful to figure out the best format and bpc count for
a given mode.

Most HDMI drivers have some code to calculate the TMDS character rate,
usually to adjust an internal clock to match what the mode requires.
Since the TMDS character rates mostly depends on the resolution, whether
we need to repeat pixels or not, the bpc count and the format, we can
now derive it from the HDMI connector state that stores all those infos
and remove the duplication from drivers.

A lot of the various HDMI drivers duplicate some logic that depends on
the HDMI spec itself and not really a particular hardware
implementation.
Output BPC or format selection, infoframe generation are good examples
of such areas.
This creates a lot of boilerplate, with a lot of variations, which makes
it hard for userspace to rely on, and makes it difficult to get it right
for drivers.
In the next patches, we'll add a lot of infrastructure around the
drm_connector and drm_connector_state structures, which will allow to
abstract away the duplicated logic. This infrastructure comes with a few
requirements though, and thus we need a new initialization function.
Hopefully, this will make drivers simpler to handle, and their behaviour
more consistent.

The "struct dma_fence_array" can be refactored to add a flex array in order
to have the "callback structures allocated behind the array" be more
explicit.
Do so:
- makes the code more readable and safer.
- allows using __counted_by() for additional checks
- avoids some pointer arithmetic in dma_fence_array_enable_signaling()
