[PARISC] pdc_console: fix bizarre panic on boot

Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug
by accidently removing the "static" from iodc_dbuf. This resulted in, what
appeared to be, a trap without *current set to a task. Probably the result of
a trap in real mode while calling firmware.

Also do other misc clean ups. Since the only input from firmware is non
blocking, share iodc_dbuf between input and output, and spinlock the
only callers.

[PARISC] print more than one character at a time for pdc console

There's really no reason not to print more than one character at a
time to the PDC console... Booting is measurably speedier, and now I don't
have to watch individual characters get drawn.

There's no reason why we shouldn't be using _irqsave instead of
_irq for any of these calls. fwiw, this fixes the
"start_kernel(): bug: interrupts were enabled early" message displayed
on bootup recently.

We were assigned an OS_ID of 0x0006. Consistently use OS_ID_LINUX

Check PDC_CACHE to see if spaceid hashing is turned on, and fail to
boot if that is the case.

However, some old machines do not implement the PDC_CACHE_RET_SPID
firmware call, so continue to boot if the call fails because of
PDC_BAD_OPTION (but fail in all other error returns).
