Link training is not retried in automated link training request.
In case link training is occasionally failing, there is not way to retry
so the requested lane settings will not set.

1. Change 100104: Move verify link cap after read edid causes MST
link_cap struct not being set. It leads to zero denominator
pbn_per_slot value, leading to the crash at
dal_fixed31_32_div(). Skip MST link training for now and will
need to add MST specific link traning routine later.
2. Change 98822: Adding edp supports changes link setting
condition from max_link to verified_link. It leads to MST is
getting wrong link settings.
e.g. LINK_SPREAD_05_DOWNSPREAD_30KHZ not set in MST case

Audio should be attached to the same pipe once it is attached.
We will not remove audio endpoint in disable stream.
We will reeanble the audio after automated link training test

Removed FBC disable from dc_enable_stereo().
It should be implemented in stereo_setup callback, which is not
implemented yet. Otherwise it always disable FBC regardless
if stereo supported or not.

Previously atomic_check assumed that dc_state is allocated and filled
in. This is not the case when we hit EDEADLK and have to backup and
retry.
We could change atomic_state_clear but that revealed some other
problems. For now let's create and construct dc_state in atomic_check.

Until now new context would start as empty, then populated
with exsisting pipes + new. Now we start with duplication
of existing context and then add/delete from the context
pipes as needed.
This allows to do a per stream resource
population, start discarding dc_validation_set
and by this brings DC closer to to DRM.
v2: Add some fixes and rebase.

Current ref_count inc/dec is not guarded by locks which leads to
a raced condition where two threads try to access the variable
at the same time. In this case, both might act on the same cached
value and inc/dec from the same value, rather than inc/dec by 2.
