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.

DSI PLL is tightly coupled with DSI PHY. This change removes
separate DSI pll driver and makes DSI pll as a subnode to DSI
PHY which is an accurate way of representation. In addition, this
change adds support for 5nm DSI ctrl and PHY revisions and adds
DSI pll support for 5nm. Remove support for older DSI pll revisions
such as 7nm, 10nm, 14nm, 20nm, 28nm.
