drm/msm/dpu: drop VBIF index from the struct dpu_hw_vbif

Browse Source 
Since we don't support and don't use VBIF_NRT, VBIF_RT is the only
possible VBIF type. To simplify the driver, drop vbif_idx from the VBIF
instance structure. As the last users of VBIF_RT and enum dpu_vbif are
gone, drop them too.
