565f95d64f libcamera: pipeline: simple: Try next mbus code if setupFormats() fails
Now SimpleCameraData::setupFormats() can fail if the camera sensor
supports media bus code which some entities down the pipeline don't.

When this happens continue with the next media bus code instead of
aborting the enumeration of the possible pipeline configurations.

3e7aa49344 libcamera: pipeline: ipa: raspberrypi: Use dma heap allocs for LS tables
Remove use of vcsm allocations and replace with dma heap allocations.
The pipeline handler now passes the fd of the allocation over to the IPA
instead of the raw pointer.

Also use libcamera::FileDescriptor for fd lifetime management.

This commit must be built alongside the accompanying BCM2835 ISP kernel
driver changes at https://github.com/raspberrypi/linux/pull/3715.
Otherwise a mismatch will cause undefined behavior.

2c0fad508c libcamera: pipeline: raspberrypi: Start IPA when starting camera
The IPA is meant to be started when starting the camera, and stopped
when stopping it. It was so far started early in order to handle the
IPAInterface::processEvent() call related to lens shading table
allocation before IPAInterface::configure() to pass the table to the
IPA. Now that the lens shading table is passed through configure(),
starting the IPA early isn't needed anymore.

89682ea1c4 ipa: raspberrypi: Pass sensor config back from configure()
The Raspberry Pi IPA uses the custom RPI_IPA_ACTION_SET_SENSOR_CONFIG
frame action to send the sensor staggered write configuration to the
pipeline handler when the IPA is configured. Replace this ad-hoc
mechanism by passing the corresponding data back from the IPA to the
pipeline handler through the configure() response. This allows
synchronous handling of the response on the pipeline handler side.

b80c01843c libcamera: ipu3: imgu: Use specific functions to configure each sink
When the IPU3 pipeline only provided streams to applications that came
from the ImgU it made sense to have a generic function to configure all
the different outputs. With the addition of the RAW stream this begins
to be cumbersome to read and make sense of in the PipelineHandlerIPU3
code. Replace the generic function that takes a specific argument for
which sink to configure with a specific function for each sink.

This makes the code easier to follow as it's always clear which of the
ImgU sinks are being configured without knowing the content of a
generically named variable. It also paves the way for future
improvements.
