[PATCH v2 5/7] drm/msm/dpu: use MDSS data for programming SSPP

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

Switch to using data from MDSS driver to program the SSPP fetch and UBWC
configuration. As a side-effect, this also swithes the DPU driver from
DPU_HW_UBWC_VER_xx values to the UBWC_x_y enum, which reflects
the hardware register values.
