drivers/intel/touch: Conditionally add ACPI _PRW based on wake source

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.
