[0/3] Cooperate with DSI RX devices to modify dsi funcs and delay mipi high to cooperate with panel sequence

In order to match the changes of DSI RX devices (for example, anx7625), 
the poweron/poweroff of dsi is extracted from enable/disable and 
defined as new funcs (pre_enable/post_disable).

The delayed MIPI signal is pulled high from LP00 to LP11, 
in order to match the power-on sequence of the panel.

Jitao Shi (3):
  drm/mediatek: dsi fine tune the dsi poweron flow
  drm/mediatek: dsi bridge implement pre_enable and post_disable
  drm/mediatek: keep dsi as LP00 before dcs cmds transfer

This is series a bug-fix or new feature (If anx7625 has never work in
upstream and this series would make support anx7625, this is new
feature) If this is a bug-fix, add Fixes tag [1] in patches.
