evdev: Drop obsolete accelerometer reject rule

Browse Source 
This rule triggers for devices with an ABS_X/Y evaluators and no
keyboard or multitouch events.  There is no way we would ever add such
a device as a pointer, keyboard or touch device anyway.  A pointer
device requires has_button (in which case the !has_key condtion would
fail); a keyboard device would also mean !has_key is false and a touch
screen device implies that !device->is_mt is false.
