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.

Prerequisites: [1]

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

Dmitry Baryshkov (3):
  drm/msm: move utility functions from msm_drv.c
  drm/msm/dpu: simplify clocks handling
  drm/msm/dp: rewrite dss_module_power to use bulk clock functions
