The VIN Gen3 hardware don't have Line Post-Clip capabilities as VIN Gen2
hardware have. To protect against writing outside the capture window
enable field toggle after a set number of lines have been captured.
Capturing outside the allocated capture buffer where observed on R-Car
Gen3 Salvator-XS H3 from the CVBS input if the standard is
misconfigured. That is if a PAL source is connected to the system but
the adv748x standard is set to NTSC. In this case the format reported by
the adv748x is 720x480 and that is what is used for the media pipeline.
The PAL source generates frames in the format of 720x576 and the field
is not toggled until the VSYNC is detected and at that time data have
already been written outside the allocated capture buffer.
With this change the capture in the situation described above results in
garbage frames but that is far better then writing outside the capture
buffer.

The group objects assume linear indexing, and more so always assume that
channel 0 of any active group is used.
Now that the CRTC objects support non-linear indexing, adapt the groups
to remove assumptions that channel 0 is utilised in each group by using
the channel mask provided in the device structures.
Finally ensure that the RGB routing is determined from the index of the
CRTC object (which represents the hardware DU channel index).

The DU CRTC driver does not support distinguishing between a hardware
index, and a software (CRTC) index in the event that a DU channel might
not be populated by the hardware.
Support this by adapting the rcar_du_device_info structure to store a
bitmask of available channels rather than a count of CRTCs. The count
can then be obtained by determining the hamming weight of the bitmask.
This allows the rcar_du_crtc_create() function to distinguish between
both index types, and non-populated DU channels will be skipped without
leaving a gap in the software CRTC indexes.

Despite never getting called from atomic context,
usb URB memory allocations use GFP_ATOMIC, which does not sleep
for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.

And I also manually check it.
