msm: mdss: Unblock PP and hist ioctls when PU is enabled

Currently driver has checks to ensure that partial update feature
and post-processing feature are mutually exclusive. Ideally, this
enforcement should be done by clients of PP driver. This patch
removes all the partial update status checks for PP ioctls.
