Subject: drm/msm/mdp5: Drop clock names with "_clk" suffix
Git-commit: d0538f5048fafe5633c58f25c3332f67739cdeb4
Patch-mainline: v4.13-rc5
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

We have upstream bindings (msm8916) that have the "_clk" suffix in the
clock names. The downstream bindings also require it.

We want to drop the "_clk" suffix and at the same time support existing
bindings. Update the MDP5 code with the the msm_clk_get() helper to
support both old and new clock names.
