Because the USB keyboard tells us which keys it has, we don't need a
scancode->keycode table. (We have something like that in the HID driver,
because the HID codes aren't the same as Linux keycodes, but the table
is fixed.)

For PS/2 you unfortunately cannot have a fixed table, and thus
EVIOCSKEYCODE is needed. 

Btw, the classic KD* scancode loading ioctls should now be supported as
well.
