[PATCH] input: psmouse option parsing

From: Dmitry Torokhov <dtor_core@ameritech.net>

With Vojtech's approval adjusted psmouse option names by dropping psmouse_
prefix.

If psmouse is compiled as a module new option names are: proto, rate,
resetafter, resolution, smartscroll

If psmouse is built in the kernel the prefix "psmouse." is required in
front of an option, like "psmouse.proto"

Also, since we are changing all names, killed psmouse_noext completely
