[PATCH v4 0/2] drm/msm: rework clock handling

[Dmitry Baryshkov]

msm_dss_clk_*() functions significantly duplicate clk_bulk_* family of
functions. Drop custom code and use bulk clocks directly. This also
removes dependency of DP driver on the DPU driver internals.

Changes since v3:
 - Switched to devm_clk_bulk_get_all() per Stephen's suggestion.
 - Removed a call to of_clk_set_defaults() (per Stephen's suggestion
   again). It duplicates a call in platform_probe().
 - Split the first patch (moving helpers to msm_io_utils.c), it's unused
   now.

Changes since v2:
 - Retain conditional code/prints in DP code to ease debugging
 - Rebase on top of msm-next and [1]
 - Split helper functions to msm_io_utils.c as suggested by Jessica

Changes since v1:
 - Rebase on top of current tree to fix conflicts
