The RGB444 format swapped the red and blue components, fix this.
Rather than making a new BGR444 format (as I proposed initially), Jon prefers
to just fix this and return the colors in the right order. I think that makes
sense in this case.
Since the RGB444 pixel format is deprecated due to the ambiguous specification
of the alpha component we use the XRGB444 pixel format instead (specified as having
no alpha channel).

Two reasons for this: the v4l2_ctrl_handler_init() call must come

its controls should be added to the bridge driver), and the
v4l2_ctrl_handler_free() call at the end should only be called if

Various formats had their byte ordering implemented incorrectly, and

get V4L2_PIX_FMT_YVYU.
This was working before commit ad6ac45222
("add new formats support for marvell-ccic driver"). That commit broke
the original format support and the OLPC XO-1 laptop showed wrong
colors ever since (if you are crazy enough to attempt to run the latest
kernel on it, like I did).
The email addresses of the authors of that patch are no longer valid,
so without a way to reach them and ask them about their test setup
I am going with what I can test on the OLPC laptop.
If this breaks something for someone on their non-OLPC setup, then

that commit went in untested.

This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put
memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the
prepare/finish memops.
Now that vb2-dma-sg will sync the buffers for you in the prepare/finish
memops we can drop that from the drivers that use dma-sg.
For the solo6x10 driver that was a bit more involved because it needs to
copy JPEG or MPEG headers to the buffer before returning it to userspace,
and that cannot be done in the old place since the buffer there is still
setup for DMA access, not for CPU access. However, the buf_finish
op is the ideal place to do this. By the time buf_finish is called
the buffer is available for CPU access, so copying to the buffer is fine.

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

This patch adds the SOFx/EOFx pair check for marvell-ccic.
When switching format, the last EOF may not arrive when stop streamning.
And the EOF will be detected in the next start streaming.
Must ensure clear the left over frame flags before every really start streaming.

This patch adds the reset ccic phy operation when stop streaming.
Stop streaming without reset ccic phy, the next start streaming
may be unstable.
Also need add CCIC2 definition when PXA688/PXA2128 support dual ccics.

Remove g_chip_ident. This driver used some of the V4L2_IDENT defines, replace
those with a driver-specific enum. This makes it possible to drop the
v4l2-chip-ident.h define as well.

This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

It makes sense to latter break it into a few other dirs.
