rombios: Remove annoying 3-second boot delay waiting for user to hit
F10 to select boot device. This will be rarely used, and it is
possible to hit F10 before the message is displayed and the keypress
will still register. So in practice it is quite possibel to use this
boot feature reliably without needing a multi-second delay.
