[PATCH v3 27/46] media: rkisp1: isp: Pass mbus type and flags to rkisp1_config_cif()

[Laurent Pinchart]

To prepare for the removal of the active_sensor field from the
rkisp1_device structure, pass the media bus type of flag to the
rkisp1_config_cif() function instead of accessing them through
active_sensor.
