Add "notime" boot option to prevent timing data from being printed on
each printk message line.

We've seen a few cases of 'time' data locking problems (possibly
involving netconsole or net drivers). If a kernel is built with
CONFIG_PRINTK_TIME=y, it may have a boot locking hang. Booting
with "notime" may (i.e., could) prevent the lock hang and allow the
kernel to boot successfully, without requiring a kernel rebuild.

Wonderful, now we have _three_ options to control time...

time=<bool>
printk.time=<bool>
notime=<bool>

Currently the middle one is "printk.printk_time".
And the first and last are just "time" and "notime", without a bool value.

And as I wrote later, I'd be happy to remove #s 1 and 3 and use only the
middle one, renaming the param so that it _is_ printk.time.
