In order to facilitate this, keep panel TE enabled in video mode
operation until it is aligned with vysnc.

This change enforces dp, dsi and the sde drivers to use the
drm framework defined dsc_config data structure. As a part of this,
it introduces the sde_dsc_helper API to configure the dsc params
and creating a PPS command. Earlier each driver implemented it's
private versions leading to duplication of code. Additionaly the
helper api supports DSC spec 1.2 422 and 420 mode.
