Revert "msm_fb: Correctly setup splash screen flag in MDP probe"

This reverts commit d8bad5aaad6a19d65ae8d63451044455aceca46a.
msm_fb: Fix display corruption with continuous splash screen feature

During boot up, we observe random lines on screen between the
splash_screen image and the android animation. MDP clocks
were turned off during bootup. Fix this issue by enabling
the clocks when this feature is enabled.

Add check to see that the video mode engine is not busy before
turning off the dsi controller to avoid any underruns.
