ACPI: TAD: Use DC wakeup only if AC wakeup is supported
According to Section 9.17.2 of ACPI 6.6 [1], setting ACPI_TAD_DC_WAKE in
the capabilities without setting ACPI_TAD_AC_WAKE is invalid, so don't
support wakeup if that's the case.
Moreover, it is sufficient to check ACPI_TAD_AC_WAKE alone to determine
if wakeup is supported at all, so use this observation to simplify one
check.
