Now that binutils patch has been backported to every Buildroot binutils
version we can drop nios2 binutils bug 27597 dependency.

With upstram commit [1] (since version v0.1.0) the pipeline option 'raspberrypi'
was renamed to 'rpi/vc4'.
Change the buildroot option name from BR2_PACKAGE_LIBCAMERA_PIPELINE_RASPBERRYPI
to BR2_PACKAGE_LIBCAMERA_PIPELINE_RPI_VC4 (and add Config.in.legacy entry
accordingly) and move handling in Config.in/libcamer.mk to follow alphabetic
ordering.
Fixes:

This brings in support for OV5675 and IMX477 camera sensors, exposes
autofocus controls through the libcamera API, adds support for more
pixel and media bus formats, fixes AWB on IPU3, improves gstreamer
support and numerous other improvements and fixes.
Since commit fcb0ea001a2d "libcamera: Introduce YamlParser as a helper
to parse yaml files", libyaml is a required dependency since YAML is
used for configuration/tuning files.

The hardware related pipelines are obviously not available on other
architectures.
As suggested by upstream [0], add a dependency on arm or aarch64 for
RaspberryPi pipeline, to avoid the following build failure with a

Additionally, as Kieran puts it:
I'd go further and filter the IPU3 on only x86 for instance, and the
RKISP on (arm||aarch64).
So be it.

The ControlValue structure is currently defined with a 16-bit hole
(causing unaligned access to the numElements_ field, though that's a
separate topic).
This structure has a static assertion to ensure that its size does not
change without due care, as it forms part of our ABI and is used in
Serialisation between the pipeline handlers and IPA components.
The m68k architecture is the only target which fails this assertion,
which is likely because it can pack the structure more efficiently,
producing a different binary size.
This is likely an area we will tackle before stabilising our ABI, but
until then, disable m68k builds as libcamera is not expected to be
supported on this target.

Cameras are complex devices that need heavy hardware image processing
operations. Control of the processing is based on advanced algorithms
that must run on a programmable processor. This has traditionally been
implemented in a dedicated MCU in the camera, but in embedded devices
algorithms have been moved to the main CPU to save cost. Blurring the
boundary between camera devices and Linux often left the user with no
other option than a vendor-specific closed-source solution.
To address this problem the Linux media community has very recently
started collaboration with the industry to develop a camera stack that
will be open-source-friendly while still protecting vendor core IP.
libcamera was born out of that collaboration and will offer modern
camera support to Linux-based systems, including traditional Linux
distributions, ChromeOS and Android.
The project has not made an official release as of yet, so we're
using the latest sha1 from master
We utilise C++ 11 but we mandate GCC5+ due to a bug [0] in earlier
versions which result in compile failures on our code base.
