[PATCH v4 8/9] drm/msm/dpu: merge DPU_SSPP_SCALER_QSEED3, QSEED3LITE, QSEED4

[Dmitry Baryshkov]

Three different features, DPU_SSPP_SCALER_QSEED3, QSEED3LITE and QSEED4
are all related to different versions of the same HW scaling block.
Corresponding driver parts use scaler_blk.version to identify the
correct way to program the hardware. In order to simplify the driver
codepath, merge these three feature bits.
