Subject: [PARISC] Update parisc specific input code from parisc tree

Update drivers to new input layer changes.

Signed-off-by: Helge Deller <deller@parisc-linux.org>
Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>

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.
