ASoC: rk3308_codec: clean up and add support headphone detection

Since this signal line is directly connected to the GIC,
it has not been processed by the logic gate. Therefore,
when the headphone is plugged in, the status register
will remain high and when pulled out, the status register
will be converted to a low level.

However, the GIC can only accept high and rising edge
triggers, so when the headset is plugged in, it needs to
poll (~2s) to detect whether plug the headphone.
