arm64: dts: rockchip: Fix the headphone detection on the orangepi 5

The logic of the headphone detect pin seems to be inverted, with this
change headphones actually output sound when plugged in.

Does not need workaround of using pin-switches to enable output.

Verified by checking /sys/kernel/debug/gpio.
