Input: serio - offload resume to kseriod

When resuming AUX ports psmouse driver calls psmouse_extensions()
to determine if the attached mouse is still the same, which may take
a while to complete for generic mice. Offload the resume process to
kseriod so the rest of the system may continue resuming without
waiting for the mouse.
