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.

Preserve original dsi-off sequence to remove DMA failure. Previously the power
off sequence was modified to resolve display turn on/off issue, but the changes
were not necessary in current kernel and just caused side effects which
resulted in fb_blank being stuck due to occasional DMA failures.
This reverts commit e1a9b1bda7691e4f62728d09e1993eb9ae9db8d6.

There has VG1 pipe commit (pan display) happen after system
suspended. This left VG1 still staged up at mdp mixer. Once timing
generator is enabled at resume, VG1 pipe start fetching contents from
address 0 since VG1 has not yet be configured. This cause page fault.
This patch has sanity check at system suspend to make sure no any pipe
stage up at mixer after suspend.

An earlier commit(ec5b2f)increased the number of reserved fields
in the kernel standard fb.h header changing the struct size.
This caused issues with userland applications using the corresponding
bionic header. This patch revert the earlier increas in size
and makes corresponding adjustments to the reserved field usage.
A follow up patch will remove usage of reserved fields entirely.

lcd should be done before backlight on and turning off backlight
should be finished before lcd off. But current implementation
doesn't guarantee these on/off sequence. This patch ensure the
