[PATCH 4/6] drm/msm/mdp: Remove CONFIG_OF checks from MDP drivers

[Archit Taneja <architt@codeaurora.org>]

We don't intend to use downstream non-DT kernels anymore, so remove
CONFIG_OF checks.

Update the TODO comment so that we don't forget about max_clk setting
for non APQ8064 chips having MDP4.
