media: st-mipid02: Propagate format from sink to source pad

When setting formats on the sink pad, propagate the adjusted format over
to the subdev's source pad. Use the MIPID02_SOURCE macro to fetch the
pad's try format rather than relying on the pad field of the format to
facilitate this - the function is specific to the source pad anyway.
