So far we've sort of protected the global state under dev_priv with
the connection_mutex. I wan to change that so that we can change the
cdclk even for pure plane updates. To that end let's formalize the
protection of the global state to follow what I started with the cdclk
code already (though not entirely properly) such that any crtc mutex
will suffice as a read lock, and all crtcs mutexes act as the write
lock.
We'll also pimp intel_atomic_state_clear() to clear the entire global
state, so that we don't accidentally leak stale information between
the locking retries.
As a slight optimization we'll only lock the crtc mutexes to protect
the global state, however if and when we actually have to poke the
hw (eg. if the actual cdclk changes) we must serialize commits
across all crtcs so that a parallel nonblocking commit can't get
ahead of the cdclk reprogamming. We do that by adding all crtcs to
the state.
TODO: the old global state examined during commit may still
be a problem since it always looks at the _latest_ swapped state
in dev_priv. Need to add proper old/new state for that too I think.
v2: Remeber to serialize the commits if necessary

On platfroms with gen10+ display, driver must set the enable bit of
AUDIO_PIN_BUF_CTL register before transactions with the HDA controller
can proceed. Add setting this bit to the audio power up sequence.
Failing to do this resulted in errors during display audio codec probe,
and failures during resume from suspend.
Note: We may also need to disable the bit afterwards, but there are
still unresolved issues with that.

When audio power domain is suspended, the display driver must
save state of AUD_FREQ_CNTRL on Tiger Lake and Ice Lake
systems. The initial value of the register is set by BIOS and
is read by driver during the audio component init sequence.

enum port is a mess now because it no longer matches the spec
at all. Let's start to dig ourselves out of this hole by
reducing our reliance on port_name(). This should at least make
a bunch of debug messages a bit more sensible while we think how
to fill the the hole properly.
Based on the following cocci script with a lot of manual cleanup
(all the format strings etc.):

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.
There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.
v2: fix the include guard name in the renamed file

Use port_clock to check the clock values in n/cts lookup table instead
of crtc_clock. As port_clock is already adjusted based on color mode set
(8 bit or deep color), this will help in checking clock values for deep
color modes from n/cts lookup table.
