This change fixes issues which causes corruption for dual dsi
dsc panel. It fixes the number of slices configured on
dsc hw block and handles deriving correct picture width from
mode timings. Additionally it fixes the core max buffer sizes
used by the hw block.

Add a generic API which calculates the horizontal timings based
on the compression type in case compression is enabled and even
for non-compression cases.
Replace the usage of the DSC macros with this generic API.

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.

change pending flag needs to be set after it has been calculated.
