media: imx-mipi-csis: Pass format explicitly to internal functions

To prepare for usage of the subdev active state that will replace the
csis_fmt and format_mbus fields stored in the mipi_csis_device
structure, pass the format explicitly to the functions called when
starting streaming to avoid accessing those two fields. Not functional
change intended.
