ec/google/chromeec/acpi/cros_ec: Ensure GpioInt and _PRW are mutually exclusive
Under Windows ACPI, GpioInt and _PRW must be mututally exclusive within the scope of a device, otherwise a BSOD occurs with an ACPI_BIOS_ERROR. To enforce this, only use _PRW when EC_ENABLE_SYNC_IRQ_GPIO is not set. If both EC_ENABLE_WAKE_PIN and EC_ENABLE_SYNC_IRQ_GPIO are set, then ensure that the GpioInt is flagged as ExclusiveAndWake (vs just Exclusive) so that the CREC device is still able to wake the device as needed. TEST=Build/boot google/{nocturne,frostflow} to Win11 w/ sync_irq_gpio and wake_pin both enabled.
