msm_fb: Fix panel not turning on.

While the panel successfully turns on in early boot, that is only because it is
using direct framebuffer mode. While in Android, a different path is used.
Always power the panel after commit.

Revert "mddi: Remove clk_set_max function."

Apparently some devices require this function to initialize MDDI properly.

This reverts commit e06115ea4566491e864d72ff1f1568fc91981456.
