mb/google/guybrush: Use open drain eSPI alerts

Remove the override in guybrush devicetree that configured in-band eSPI
alerts. This will result in guybrush using dedicated open-drain eSPI
alerts. Guybrush boards must be reworked to connect the eSPI alert line,
otherwise they will not boot with this change
