'struct v4l2_mbus_config' is a legacy struct that should not be used
in new drivers. So replace it with the fields:
enum v4l2_mbus_type mbus_type;
unsigned int parallel_bus_flags;
The field 'parallel_bus_flags' is used only for buses of types
V4L2_MBUS_BT656, V4L2_MBUS_PARALLEL which are not yet supported
so they are set to 0.
