Add optional <mbus_code> arg to all 'v4l2-ctl --list-formats-*'
commands. If <mbus_code> is given and the device has capability
V4L2_CAP_IO_MC then list only the formats that matches the
mbus code.
If <mbus_code> is given and the device doesn't have this
capability then print an error message.
Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx>

The patch is only tested on the capture devices of vimc driver,
and for the error message on vivid driver.
