This line has been added in commit ef74679a810fe6858f625b9d52b68cc3fc61eb3d with
other initializations. However, scancode set 0 doesn't exist (only 1, 2, 3).
This works well as long as operating system is resetting keyboard, or overwriting
the current scancode set with the one it wants.
This fixes IBM 40p firmware, which doesn't bother sending KBD_CMD_RESET or KBD_CMD_SCANCODE.

Matches reset behavior documented at
http://www.computer-engineering.org/ps2keyboard/ (the best source
I could find for the PS/2 specs).

Michael, do you want to merge this through the PC tree?
