Display Port monitor could support kinds of mode which indicate
in monitor edid, not just one single display resolution which
defined in panel or devivetree property display timing.
Note: Gustavo Padovan try to remove the controller and phy
power on function in bind time at bellow commit:
drm/exynos: do not start enabling DP at bind() phase
But for now driver need to read edid message in .get_modes()
function, so controller must be inited in bind time, so we
need to add controller init back.
