[Why]
Update clock only when non-seamless boot stream exists
creates regression on multiple scenerios.

[How]
Update clock in two conditions
1. Non-seamless boot stream exist.
2. Stream_count = 0

[Why]
HDMI requires fallback to TMDS by redetection
in order to switch PHY settings.
This avoids black out when link training fail
during mode setting, link quality update,
disable driver sequence.

[How]
Allow driver to redetect HDMI displays
based on retraining or fallback mechanism.

[Why]
When running a game/benchmark with v-sync disabled, disabling a plane
(which is v-sync) can cause an underflow. This is due to flips that are
pending before pipe locking being applied after locks are released and
pipes have been re-arranged or disconnected. This can potentially apply
a flip on the incorrect pipe.

[How]
Check that any pending flips are cleared before locking any pipes to
ensure flips are applied on the correct pipes.
