[PATCH] input / keyboard / Scancode Set 3 support broken

If somebody uses keyboard scancode set 3 it is necessary to explicitly
program the keyboard to send make/break codes for all keys and to set
autorepeat for all keys.

This is critical for some people.  One example is the LK461/46W series
of keyboards from Digital Equipment Corporations.  These are VMS
keyboards that are also usable on a normal PC.

These keyboards support Scancode Set 2, but for some keys this support
is screwed up -- some function keys (e.g.  F18/F20) report the same
scancode sequence combined with both alt and shift keys.

Scancode Set 3 works perfectly if all keys are programmed to give
make/break codes.

A lot of keyboards manufactured by Cherry only make/break for some (not all!)
modifyer keys in scancode set 3 without this fix.
