USB: ftdi_sio: sort PID/VID entries in new ftdi_sio_ids.h header

This is a (almost) sort-only patch to sort FTDI device
product ID definitions in new ftdi_sio_ids.h header.

Advantage is that new device ID submissions will now have a specific (sorted)
position - less future merge conflicts.

Compile-tested, based on _current_ mainline git.
Minor checkpatch.pl warnings were eliminated whereever it made sense,
very minor text changes.
