checkpatch.pl: update $logFunctions

Previous behavior allowed only alphabetic prefixes like pr_info to exceed
the 80 column line length limit.

ath6kl wants to add a digit into the prefix, so allow numbers as well as
digits in the <prefix>_<level> printks.

<prefix>_<level>_ratelimited and <prefix>_<level>_once and WARN_RATELIMIT
and WARN_ONCE may now exceed 80 cols.

Add missing <prefix>_printk type for completeness.
