parisc: pass through '\t' to early (iodc) console

The firmware handles '\t' internally, so stop trying to emulate it
(which, incidentally, had a bug in it.)

Fixes a really weird hang at bootup in rcu_bootup_announce, which,
as far as I can tell, is the first printk in the core kernel to use
a tab as the first character.
