Hi,

The following patches implement generic suspend and resume for
input devices. As part of the suspend sequence input core will
turn off leds and bell (if they were active) and upon resume the
state of the leds, sound effects and repeat rate/delay will be
restored without requiring and special handling in individual
drivers.

The change required some additional locking in i8042/libps2 and
while I don't particularly like it the positive thing is that
the change should allow switching serio to the asynchronous
suspend and resume, i8042 should be able to handle it now.
