Provide the quanta host power control.

  systemctl start obmc-chassis-poweroff@0.target
  systemctl start obmc-chassis-poweron@0.target

Added the host-gpio.service on boot to enable the power on
and power off scripts.

Testing: The scripts were launched with the state change commands above,
however they were modified such that they didn't rely on the old
namespace.

The GPIOs basically trigger the power button on the front panel.
