Workaround for imx5x M4IF burst len errata when armv7 neon enabled, use
pgprot_writecombine instead of pgprot_noncached, to avoid burst len > 8.

If VPU doesn't use IRAM, there will be a kernel dump when
we enter VPU driver probe function.
This issue is caused by allocating IRAM with zero buffer
size.

* Remove VGA support
* Remove HDMI customization (was for the old driver)
* Consolidate DI clock setting (view is to remove it eventually since
the bug it was meant to work around is fixed)
* Remove mxc_ipuv3_fb.c dependency on EfikaMX includes
If enabled MMU, there is AXI read/write error on MX508 when run
OpenVG CTS.
Besides, change EMEM1 size to 10MB by default to make gpu driver
work on MX50_ARM2 board with 128MB memory installed.

When terminating some applications such as OpenGL ES2.0 conf. test,
kgsl_device_stop is not triggered. And run such kind of application
for several times, system hang happens for inconsistency of device
states. So make sure device is stopped in kgsl_device_close, which
is only called by last running caller process.

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:

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.
