drm/msm/sde: enable pixel extension and qseed3 along with VIG pipes

If the user-space client doesn't provide the pixel extension and qseed3
configuration, driver should set the default values. Change sets the
default values if user-space client is not configuring the blocks when
VIG pipes are selected.
