Decrease the log level for messages that are typically printed from a
real time thread execution environment (such as the display commit
thread). This can help with cases where a console lock held during the
execution of these real time threads can result in RT throttling issues.

Current implementation checks for loss of channel equilization
or clock recovery only if the sink sets the link status updated
bit in the DPCD. However, it is possible that the sink can issue
an IRQ HPD to notify a link loss without setting the link status
updated field. Update the implementation to perform a link
maintenance whenever clock recovery or channel equalization is not
ok irrespective of whether the link status updated bit is set.

Add the colorspace property for DP controller for MSM. Also, change
the default method to send the colorimetry information to the sink
from MISC bits of MSA to VSC SDP packets if the sink supports it. This
helps to avoid dynamic switches between the packet types for sending
the colorimetry information during BT2020 and DCI-P3 use-cases.

Update the link training process along with the AUX
communications during link training as per hardware
recommendations.
Update the pre-emphasis and swing values for active
lanes only instead of all lanes.
During link training, update pre-emphasis and swing
values in hardware first and then update sink.
