The code was reducing the number of raw stream buffers allocated when
the application is providing some of its own. However, it was not
taking account of the fact that the application cannot supply embedded
data buffers, so it must always allocate a reasonable minimum number
of these buffers (possibly more than the number of raw stream buffers)
to prevent frame drops.

When acquiring the media device, it is not necessary to match all entity names,
so remove it. Aditionally, we do not need to keep the MediaEntity pointers for
the Unicam and ISP devices stored within the PipelineHandlerRPi class. Instead
these can be stored locally in PipelineHandlerRPi::match().
PipelineHandlerRPi::registerCamera() now returns an int error code instead of a
boolean for pass/fail.

For simplicity, the pipeline handler currently look at the maximum number of
buffers set in the StreamConfiguration by the user and allocate the same number
of internal buffers for all device nodes. This would likely overallocate buffers
for some nodes. Rework this logic to try and minimise overallcations without
compromising performance.
The key change is to mostly decouple the number of internal buffers allocated
from number of buffers requested by the user through the StreamConfiguration.
For ISP nodes, we only ever need 1 set of internal buffers, as the hardware runs
synchronous with the requests and IPA.
For Unicam nodes, allocate a minimum for 4 buffers (exported + internal), but
also require at least 2 internal buffers to minimise frame drops.

contains a map of numerical indexes to ControlInfoMap instances.
This is a leftover of the old IPA protocol, where it was not possible to

ControlInfoMap was indexed by a numerical id and stored in a map.
Now that the IPA interface allows to specify parameters by name, drop the

can be added to IPAConfigInfo.

The V4L2VideoDevice::toV4L2PixelFormat() function is incorrectly
implemented, as it will pick a multi-planar format if the device
supports the multi-planar API, even if only single-planar formats are
supported. This currently works because the implementation calls
V4L2PixelFormat::fromPixelFormat(), which ignores the multiplanar
argument and always returns a single-planar format.
Fixing this isn't trivial. As we don't need to support multi-planar V4L2
formats at this point, drop the function instead of pretending
everything is fine, and call V4L2PixelFormat::fromPixelFormat() directly
from pipeline handlers. As the single-planar case is the most common,
set the multiplanar argument to false by default to avoid long lines.

Do not compare higher precision of the ratios, as it might lead to
absurd selection of sensor size for a relatively low requested
resolution size.
For example:
The imx258 driver supports the following sensor resolutions:
- 4208x3118 = 1.349583066
- 2104x1560 = 1.348717949
- 1048x780 = 1.343589744
It can be inferred that, that the aspect ratio only differs by a small
mantissa with each other. It does not makes sense to select a 4208x3118
for a requested size of say 640x480 or 1280x720, which is what is
happening currently.
($) cam -c1 -swidth=640,height=480,role=raw
- CIO2 configuration: 4208x3118-SGRBG10_IPU3 [*]
In order to address this constraint, only compare the ratio with single
precision to make a better decision on the sensor resolution policy
selection.

- CIO2 configuration: 1048x780-SGRBG10_IPU3 [*]

Modify the frame size selection procedure to prioritize resolutions
with the same FOV as the sensor's native one, to avoid cropping in the
sensor pixel array.
For example:
- on a Soraka device equipped with ov13858 as back sensor, with a
native resolution of 4224x3136 (4:3), when requested to select the
sensor output size to produce 1080p (16:9) a frame size of 2112x1188
(16:9) is selected causing the ImgU configuration procedure to fail.
If a resolution with the same FOV as the sensor's native size, such
as 2112x1568 (4:3), is selected the pipeline works correctly.

This prepares a base to introduce custom selection of sensor format
based on platform(Soraka or Nautilus) constraints. The changes in
selection policy will be introduced in a subsequent patch.
The function is copied from CameraSensor::getFormat() in the IPU3
pipeline handler code to be later changed on top.
The copy is not verbatim and has a minor change as follows:
CameraSensor::getFormats() has access to a V4L2Subdevice::Formats
internally and use it directly to iterate over supported camera sensor
frame sizes. The copy is adapted to use the CameraSensor::sizes(mbusCode)
instead, to enumerate over the supported frame sizes as per

In CameraSensor, the mbusCodes() and sizes() accessor functions
retrieves all the supported media bus codes and the supported sizes
respectively. However, this is quite limiting since the caller
probably isn't in a position to match which range of sizes are
supported for a particular mbusCode.
Hence, the caller is most likely interested to know about the sizes
supported for a particular media bus code. This patch transforms the
existing CameraSensor::sizes() to CameraSensor::sizes(mbuscode) to
achieve that goal.
The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline
handler to CIO2Device::sizes(PixelFormat) on a similar principle. The
function is then plumbed to CameraSensor::sizes(mbusCode) to enumerate
the per-format sizes as required in
PipelineHandlerIPU3::generateConfiguration().
