[PATCH v1 2/3] drm/msm/edp: add support for next gen edp

[Sankeerth Billakanti <sbillaka@xxxxxxxxxxxxxx>]

The eDP controller and phy hardware for the next generation
snapdragon platform has a different desgin compared to their
earlier generations. So, there is a need to implement new
sequences in driver software for the new hardware.

This change will implement the required seuqences to enable
eDP interface on the next generation snapdragon platforms.
