libcamera: ipu3: cio2: Consolidate information about formats

Browse source 
Instead of spreading the mapping between media bus codes and V4L2 FourCC
all over the CIO2 code collect it in a single map and extract the data
from it. This is done in preparation of adding PixelFormat information
to the mix.
