Add a DRIVERS_PS2_KEYBOARD option which controls the PS2 keyboard 

initialization.  Not all payloads require it and some keyboards take a
long time to init.

help
Enable this option to initialize PS2 keyboards found connected
to the PS2 port. Some payloads (eg, filo) require this
option. Other payloads (eg, SeaBIOS, Linux) do not require
it. Initializing a PS2 keyboard can take several hundred
milliseconds.
If you know you will only use a payload which does not require
this option, then you can say "n" here to speed up boot time.
Otherwise say "y".
