Input: i8042 - use pr_<level>, pr_fmt, fix dbg and __FILE__ use

Standardized message logging prefixes.
Removed \n from dbg macro, added \n to each dbg call site.
Removed direct use of __FILE__ from dbg, converted to pr_fmt(fmt)
Added non-debug printf argument verification of dbg calls
Removed "i8042.c" from printks, converted to pr_<level>
