Since enabling VMID takes a runtime PM reference there is no need to
suppress suspend when doing a runtime suspend. Similarly the digital
inputs and outputs are DAPM widgets and therefore the ASoC core will
be holding a reference for them.
This used to be required when integration with system suspend was being
bodged.

Happy with this. Will apply when I fully understand 1/2.

The jack detection code holds runtime PM references when required so
there is no need for suspend to do any checks.
