[PATCH v5 6/6] drm/msm/dpu: move VBIF blocks handling to dpu_rm

Move handling of VBIF blocks into dpu_rm. This serves the purpose of
unification of handling of all hardware blocks inside the DPU driver.
This removes hand-coded loops in dpu_vbif (which look for necessary VBIF
instance by looping through the dpu_kms->hw_vbif and comparing
vbif_idx).
