libcamera: ipu3: imgu: Calculate ImgU pipe configuration
Instrument the ImgU component to dynamically calculate the image
manipulation pipeline intermediate sizes.
To correctly configure the ImgU it is necessary to program the IF, BDS
and GDC sizes, which are currently fixed to the input frame size.
The procedure used to calculate the intermediate sizes has been ported
from the pipe_config.py python script, available at:
https://github.com/intel/intel-ipu3-pipecfg
at revision:
61e83f2f7606 ("Add more information into README")
Define two structures (ImgUDevice::Pipe and ImgUDevice::PipeConfig)
to allow the pipeline handler to supply and retrieve configuration
parameters from the ImgU.
Finally, add a new operation to the ImgUDevice that calculates
the pipe configuration parameters based on the requested input and
output sizes.
