drivers/input/serio/hp_sdc.c: fix crash when removing hp_sdc module
On parisc machines, which don't have HIL, removing the hp_sdc module
panics the kernel. Fix this by returning early in hp_sdc_exit() if no HP
SDC controller was found.
Add functionality to probe for the hp_sdc_mlc kernel module (which takes
care of the upper layer HIL functionality on parisc) after two seconds.
This is needed to get all the other HIL drivers (keyboard / mouse/ ..)
drivers automatically loaded by udev later as well.
