If you disable display, the display port's pin may keep high voltage which
may cause power leakage. Fix this issue by make all pin go into low level
after display disable.

drag mxc_ipuv3_fb with it (remove final efikamx specific stuff)
update some IPU stuff and ioctls for it all to interoperate
notes:
that line_length bug is still there, I really can't find why it's 0...
doesn't register because the platform_device isn't in a/a/p-mxc/devices.?
ENGR00133954 ipuv3: remove FB_SYNC_EXT flag
ENGR00133034 ipuv3: fix black flash issue during high resolution video playback
ENGR00134076 ipuv3: should not set burst size again
ENGR00133345 IPUv3 VDI:Support bottom field first setting
ENGR00131660 ipuv3: left stripe output column should be set to zero
This actually fixes the clock sync problem with the AOC HDMI monitor we have (perfectly
working display but "input not support" floating around). Happily, the boot splash
actually works, too (previously it would not work until the second set of the display
when GDM booted). Hopefully IPU support is nice and stable now.
The support for YUV422 different combinations are added
The YUV422 is supported for DI1 interface for 720P frames with 16bits bus only:
di1_primary video=mxcdi1fb:YUYV16,720P60
To define required YUV422 format use one of:
YUYV16
YVYU16
UYVY16
VYUY16
