* Remove VGA support
* Remove HDMI customization (was for the old driver)
* Consolidate DI clock setting (view is to remove it eventually since

This is a new implementation of the sii9022 driver that is clearer to follow.
The missing functionality does not seem to be causing any loss of existing
functionality and helps development, so replacing it even though it is
incomplete.
As a side effect of not doing this, the V4L driver would happily go off and touch a framebuffer address that was invalid, and there may have been a slight SNAFU with a divide by zero on the VPU framebuffer.
Arnaud Patard from Mandriva noticed these a long while ago, but now here they are.
BUG: these are temporary hacks, let's try and work out why line_length is 0..

Clk tree make default di1_clk's parent clk as pll3 when tve clk disable,
ipu disp module will re-calculate ipu pixel clk if di clk's parent clk
is not tve_clk. If blanks tve-fb0, di1 clk's parent will set to pll3,
unblank tve-fb0 need re-calculate tve clk.

Random artifacts were caused by corruption of the EPDC working
buffer. This occurred because the working buffer was being
allocated too small. This meant other accesses to FB-maintained
buffers was corrupting the working buffer and causing random
data to be drawn to the display. Fixing the working buffer size
causes the artifacts to disappear.

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

When passing di1_primay to cmdline on BBG, the modes
matching in TVE probe are successful with fb0's modes.
This causes mode match, enable TVE and do set var to fb0.
Then the fbcon var is set incorrect, fb0 var works incorrect
after resume from suspend when doing fbcon switch.
Just simply add TVE's own mode list to resolve.

Rework the display command line options to not require new option for
every new display. Add mxcdi0fb/mxcdi1fb option <fmt> and to tell system
what kind of display device is going to use.
Use "di1_primary" to make DI1 the primary display (i.e. fb0).
The display selection is done using video= parameter.
For example on imx51:
di di_fmt video_mode
DVI: 0 RGB24 mxcdi0fb:800x600M-16@60 etc
DVI-HDMI: 0 RGB24 mxcdi0fb:720P60
LVDS: 0 LVDS666 mxcdi0fb:XGA
WVGA lcd: 1 RGB565 mxcdi1fb:800x480M-16@55
TVE: 1 YUV444 mxcdi1fb:TV-NTSC
mxcdi1fb:TV-PAL
mxcdi1fb:720P60
For example on imx53:
di di_fmt video_mode
DVI: 0 RGB24 mxcdi0fb:800x600M-16@60 etc
DVI-HDMI: 0 RGB24 mxcdi0fb:720P60
WVGA lcd: 0 RGB565 mxcdi0fb:800x480M-16@55
TVE: 1 YUV444 mxcdi1fb:TV-NTSC
mxcdi1fb:TV-PAL
mxcdi1fb:720P60
If you want to set NTSC tv as primary display, and make second display
DI0 as DVI 1024x768 resolution, just add
"di1_primary video=mxcdi0fb:RGB24,1024x768M-16@60 video=mxcdi1fb:YUV444,TV-NTSC"
to cmdline.
