drm/msm/sde: add support to handle horz and vert decimation support 



This change adds the ability to disable decimation when
it is not supported. Setting decimation to true will default
it to the current maximum decimation supported by the targets.
If decimation property is not set, max horizontal and vertical
decimation will be set to 0.
