[Freedreno] [PATCH v4 0/5] drm/msm/dpu: simplify RM code

[Dmitry Baryshkov]

INTF blocks are not really handled by resource manager, they are
assigned at dpu_encoder_setup_display using dpu_encoder_get_intf().
Then this allocation is passed to RM and then returned to then
dpu_encoder. So allocate them outside of RM and use them directly.

While we are at it, drop the lm_max_width from the RM and simplify VBIF
handling (move creation/destruction to the RM too). Once this and SSPP
handling patches are merged, the RM would handle lifetime of all
dpu_hw_* objects.

Changes since v3:
 - Add missing DSPP blocks teardown
 - Remove dpu_hw_blk from dpu_hw_intf
 - move dpu_hw_vbif creation/destruction to the RM

Changes since v2:
 - Dropped DSPP, PP and MERGE_3D patches for now.

Changes since v1:
 - Split into separate patch series to ease review.

The following changes since commit 6ed95285382d6f90a3c3a11d5806a5eb7db715c3:
