This change addresses an issue in the touch driver where the ACPI _PRW
method was added unconditionally. The ACPI _PRW method should only be
generated when an Interrupt() resource is used in the _CRS method.
When a GpioInt() resource is used instead, the _PRW method is not
required.
The ACPI generation code has been updated to conditionally add the
_PRW method based on whether the wake source is a GPIO interrupt or
an IRQ interrupt. Now, the _PRW method is only added when an IRQ pin
is specified, which is consistent with ACPI requirements.
BUG=none
TEST=Configure the DRIVERS_INTEL_TOUCH option on a motherboard that
has the necessary touch configurations with wake support. Verify that
the THC ACPI tables are correctly generated in the SSDT. If wake_gpio
(i.e. GpioInt()) is used for wake, no _PRW is generated for the device.
