Some platforms, e.g. WSB, don't need jack detection when system is in Suspend, for power save reason.

Here add headphone/mic jack detection disable feature with NULL jack passed in, when disabled, it will disable interrupt, and disable LDO1, which is used for jack detection when headphone is plugged in.
