haswell: Update ChromeOS ACPI GPIO package

The chromeos_acpi driver sysfs naming is not what
crossystem expects if there is just one entry in the package
because it does not add a ".#" suffix in that case.

Specify all the expected GPIOs on wtm2 as undefined, which
should be 0xFF and not 0x00 becuase 0 is a valid GPIO.
