mainboard/ocp/monolake: Remove ACPI PNP0C0C device

Remove the empty PWRB ACPI device. The power button is controlled by
the fixed power button model in PM1x_EVT_BLK and doesn't have a
control method. The only device in mainboard.asl was PWRB, so remove
the file.

This fixes the FWTS error:
acpi_pwrb: PWR_Button field in FACP should not be zero with ACPI PNP0C0C device.
