drivers/pc80/Kconfig: Do not init PS/2 keyboard if SeaBIOS is chosen as payload
As the Kconfig description of `DRIVERS_PS2_KEYBOARD` says, SeaBIOS is
able to initialize the PS/2 keyboard itself, so it is not necessary to
let coreboot do it.
SeaBIOS is also able to do it faster as discussed in a thread on the
coreboot mailing list from October 2010 [1]. In that thread it was
also proposed to not let coreboot initialize the PS/2 coreboot when
SeaBIOS is used as a payload.
