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.

For crtcs attached to mst connectors, vcpi slots
are being allocated whether or not that crtc is
currently active. This will cause leaks during
lastclose when the crtc is inactive, because the
slots will get allocated, but never freed.
Check if the crtc state is active before
proceeding to allocate vcpi slots for that mst
connector.

Create a data structure to maintain available hardware resources
and track capabilities. This data structure is used to send
the current available resources and caps information to
connector ops get_mode_info, get_modes and validate_mode to
process the display mode.
