ACPI: TAD: Check AC wake capability before enabling wakeup
ACPI_TAD_AC_WAKE is a non-zero bit definition, so testing the macro
itself is always true. As a result, every TAD device is initialized as
a system wakeup device, including RTC-only devices and devices whose
wake capability bits were cleared because _PRW is absent.
Test the capability value returned by _GCP instead. This keeps
RTC-only TAD devices usable without advertising a wakeup capability
that the firmware does not provide.
