It is better to re-order the array, in order to put the specific standards
first, e. g. moving V4L2_STD_NTSC_443 and V4L2_STD_PAL_60 to be before V4L2_STD_NTSC
and V4L2_STD_PAL.

Also, SECAM is missing on the above table, but the driver has some tests for it.
So, I suspect that the device is capable of supporting SECAM (maybe using the same
config as for PAL_BDGHI ?).
