There's some interactions between the SCDC setup and the disconnection /
reconnection of displays. Let's document it and a solution.

During a hotplug cycle (such as a TV going out of suspend, or when the
cable is disconnected and reconnected), the expectation is that the same
state used before the disconnection is reused until the next commit.
However, the HDMI scrambling requires that some flags are set in the
monitor, and those flags are very likely to be reset when the cable has
been disconnected. This will thus result in a blank display, even if the
display pipeline configuration hasn't been modified or is in the exact
same state.
The solution we've had so far is to enable the scrambling-related bits
again on reconnection, but the HDMI 2.0 specification (Section 6.1.3.1 -
Scrambling Control) requires that the scrambling enable bit is set
before sending any scrambled video signal. Using that solution thus
breaks that expectation.
The solution used by i915 is to do a full modeset on the connector so
that we disable the video signal, enable the scrambling bit, and enable
the video signal again.
As such, we took that code and plugged it into vc4. It probably could
have been turned into an helper, but it proved to be difficult for
several reasons:
* i915 has fairly different structures than simpler KMS drivers such
as vc4, so doing some code that works with both proved to be
difficult;
* Other simpler drivers could reuse some of it (tegra, dw-hdmi), but
it would still require to move some parameters currently stored in
private structure that are needed to compute whether the scrambling
is needed or not, and then inform the driver that it needs to be
enabled. Some of those parameters are already in core structures
(drm_display_mode, drm_display_info, bpc), but the output format
isnt't. Adding it is fairly challenging since unlike the TMDS char
rate or mode, there's no consensus on what format to pick in
drivers, so it's not possible to write some generic code that can
depend on it.
For these reasons, we chose to duplicate the code for now, until someone
else really needs it as well, in which case we will be able to convert
it into a generic helper.

Our detect callback has a bunch of operations to perform depending on
the current and last status of the connector, such a setting the CEC
physical address or enabling the scrambling again.
This is currently dealt with a bunch of if / else statetements that make
it fairly difficult to read and extend.
Let's move all that logic to a function of its own.

We recently introduced a new mutex to protect concurrent execution of
ALSA and KMS hooks, and the concurrent access to some of vc4_hdmi
fields.
However, using it in the detect hook was creating a reentrency issue
with CEC code. Indeed, calling cec_s_phys_addr_from_edid from detect
might call the CEC adap_enable hook with the lock held, eventually
resulting in a deadlock.
Since we didn't really need to protect anything at the moment in the CEC
code, the decision was made to ignore the mutex in those CEC hooks,
working around the issue.
However, we can have the same thing happening if we end up triggering a
mode set from the detect callback, for example using
drm_atomic_helper_connector_hdmi_reset_link().
Since we don't really need to protect anything in detect either, let's
just drop the lock in detect, and add it again in CEC.
