disp: msm: sde: use pp dsc api only if hw supports

Bläddra i källkod 
This change checks the capabilities of pingpong block to
check if it needs to call the pingpong api to enable or
disable the dsc. Certain hw versions do not have support
in pingpong block to enable/disable the dsc instead the
dsc block itself have the hooks to control the DSC.
