[media] IR/nuvoton: address all checkpatch.pl issues 

The driver was missing KERN_ facilities on a number of printks. The
register dump functions have been updated to use KERN_INFO, so that the
register dump gets logged in syslog (they only run on driver load, and
only when debug is enabled). The buffer dump routine now uses
KERN_DEBUG, as that spew will happen quite frequently (several times
every IR signal), and shouldn't need to be logged.

Also split up the small handful of lines that were just over 80
characaters, and fixed the ioctl.h include.
