[PATCH] input: i8042 option parsing

From: Dmitry Torokhov <dtor_core@ameritech.net>

With Vojtech's approval adjusted i8042 option names by dropping i8042_
prefix.

If i8042 is compiled as a module new option names are: direct, dumbkbd,
noaux, nomux, reset, unlock.

If i8042 is build in the kernel the prefix "i8042." is required in front of
an option, like "i8042.reset"
