ASoC: rt5645: add inv_hp_det flag

The ECS EF20EA laptop use gpio for jack detection instead of rt5645
rt5645 JD. However, the GPIO polarity is inverse for hp-detect based
on the _DSD property of the RTK2 device.

Name (_DSD, Package () {
    ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
    Package () {
        Package () {"hp-detect-gpio", Package() {^RTK2, 0, 0, 1 }},
    }
})

This flag will invert the hp-detect gpio polarity.
