On at least one notebook (ECS EF20EA) the 'hp-detect' GPIO is defined in the DSDT table by the ACPI GpioIo resources in _CRS. Add this mapping to the rt5645 driver to enable the jack detection also on non-DT platforms.
Please do not merge this yet, I'll submit a V3 soon. Hans pointed out that on some BayTrail there is indeed an extra GPIO but it is used to enable the external speaker amplifier. Better to guard this by a quirk.
