[PARISC] Update parisc specific input code from parisc tree

Browse Source 
Update drivers to new input layer changes.

Reorder code in gscps2_interrupt() and only enable ports when opened.
This fixes issues with hangs booting an SMP kernel on my C360.
Previously serio_interrupt() could be called before the lock in
struct serio was initialised.
