Log:
  gptboot, zfsboot, gptzfsboot: Enable the video and serial consoles early
  
  Normally the serial console is not enabled until /boot.config is read and
  we know how the serial console should be configured.  Initialize the
  consoles early in 'dual' mode (serial & keyboard) with a default serial
  rate of 115200. Then serial is re-initialized once the disk is decrypted
  and the /boot.config file can be read.
  
  This allows the GELIBoot passphrase to be provided via the serial console.
