Checking that the captured field corresponds to the last required field
depending on the requested field order before completing the buffer
isn't enough. When the first field at stream start corresponds to the
last required field, this would result in returning an interlaced buffer
containing a single field.
Fix this by keeping track of the fields captured in the buffer, and make
sure that both fields are present for alternate field orders.

The video port doesn't support YUV formats. Disable it when the CCDC
sink pad format is set to YUV instead of leaving it enabled and relying
on downstream modules not to process data they receive from the video
port.
Experiments showed that this fixes some of the CCDC failures to stop,
especially in BT.656 mode.

Under abnormal conditions (such as glitches on the HSYNC/VSYNC signals)
the CCDC output SBL can fail to become idle. The driver currently logs
this condition to the kernel log and doesn't restart the CCDC. This
results in CCDC video capture hanging without any notification to
userspace.
Cancel the pipeline and mark the CCDC as crashed instead of hanging.
Userspace will be notified of the problem and will then be able to close
and reopen the device to trigger a reset of the ISP.

"This is a collection of header file cleanups, mostly for OMAP and

multiplatform by removing the need for mach-dependent header files
used in drivers and other places."
Fix up mostly trivial conflicts as per Olof.

Looks like the iommu framework does not have generic functions
exported for all the needs yet. The hardware specific functions
are defined in files like intel-iommu.h and amd-iommu.h. Follow
the same standard for omap-iommu.h.
This is needed because we are removing plat and mach includes
for ARM common zImage support. Further work should continue
in the iommu framework context as only pure platform data will
be communicated from arch/arm/*omap*/* code to the iommu
framework.
