Acquire the mali-c55 3a stats and parameters video devices during
::match() and plumb them in.
For this commit we simply allocate and release buffers for the
statistics and parameters. Statistics buffers are queue and dequeued
from the stats video device but their contents are for now untouched.

Add the new format describing the Mali C55's Statistics and Parameters
to videodev2. These come from the v8 of the C55 kernel driver series
[1]. Once the kernel driver is merged we can replace these temporary
manual additions with updates to the scripts that merge in the
kernel headers.

In RkISPPath::validate() the sensor sizes are correctly filtered to the
ones supported by the ISP. But later in RkISPPipeline::configure() the
configured stream size is passed to sensor->getFormat() and the
CameraSensor class chooses the best sensor format for the requested
stream size. This can result in a sensor format that is too big for the
ISP. Fix that by supplying the maximum resolution supported by the ISP
to setFormat().

In the current code, the input stage of the image resizer is used to
apply a crop to keep the aspect ratio in cases where the requested
output aspect ratio differs from the one of the selected sensor mode. On
the imx8mp the resizer hardware is not capable of cropping (for
reference see also rkisp1-resizer.c:rkisp1_rsz_set_sink_crop() in the
linux kernel v6.10).
Therefore apply the necessary cropping on the output of the ISP (on the
image stabilization block). The cropping code on the image resizer
doesn't need modifications as the requested crop gets ignored by the
kernel.
While at it, remove a todo comment that is no longer needed.

The conversions back and forth between GStreamer colorimetry and
libcamera color space are not invariant for the bt601 colorimetry.
The reason is that Rec709 transfer function defined in GStreamer
as GST_VIDEO_TRANSFER_BT709 (5), is to be replaced by its alias
GST_VIDEO_TRANSFER_BT601 (16) only for the case of bt601 (aka 2:4:16:4)
colorimetry - see [1].
Currently the composition of the GStreamer/libcamera conversions:
colorimetry_from_colorspace (colorspace_from_colorimetry (bt601))
returns 2:4:5:4 instead of the expected 2:4:16:4 (bt601). This
causes negotiation error when the downstream element explicitly
expects bt601 colorimetry.
Minimal example to reproduce the issue is with a pipeline handler
that do not set the optional color space in the stream configuration,
for instance vimc or imx8-isi:
export LIBCAMERA_PIPELINES_MATCH_LIST="vimc,imx8-isi"
gst-launch-1.0 -v libcamerasrc ! video/x-raw,colorimetry=bt601 ! fakesink
Above pipeline fails to start. This change memorizes downstream required
transfer function when mapped libcamera transfer is Rec709 in
gst_libcamera_configure_stream_from_caps(), and restores the transfer
function in gst_libcamera_stream_formats_to_caps().

Software ISP is currently fully automatic and doesn't allow image
modifications by explicitly set control values. The user has no means
to make the image looking better.
This patch introduces support for contrast control, which can improve
e.g. a flat looking image. Based on the provided contrast value, it
applies a simple S-curve modification to the image.
The contrast algorithm just handles the provided values, while the
S-curve is applied in the gamma algorithm on the computed gamma curve
whenever the contrast value changes. Since the algorithm is applied
only on the lookup table already present, its overhead is negligible.
The contrast value range is 0..2 and corresponds to the whole range from
a completely flat contrast to an infinite contrast, 1.0 being the normal
value. This makes the user visible range intuitive and easy to use in
GUI sliders, while complying with Contrast control definition. There is
no unified range in the hardware pipelines, for example rkisp1 uses
0..1.993 range while rpi uses 0..10 range.
This is a preparation patch without actually providing the control
itself, which is done in the following patch.

At present we configure raw streams by looping through the pixel
formats we support and finding one with an associated media bus
format code that the sensor can produce. In the new representation
of raw data from the kernel driver this will not work - the sensor
could produce 8, 10, 12, 14 or 16 bit data and the ISP will force
it to RAW16, which is the only actually supported output.
To fix the issue move to simply finding a pixel format with a bayer
order that matches that of the media bus format produced by the
sensor. If the sensor can produce multiple formats with the same
bayer order use the one with the largest bitdepth.
Finally, remove the claim to support RAW formats of less than 16 bits.

The latest version of the Mali C55 driver has changed the format
accepted by the ISP sink pad to be the 20-bit wide.
The CSI-2 receiver handles the format expansion internally by
propagating the sensor produced format from its sink to the 20-bit
expanded version on its source pad.
Instead of re-applying the sensor format to the CSI-2 receiver source
pad (which is now an invalid operation) read from there the format
propagated by the driver internally and further propagate it to the ISP
subdevice.
