Allow the chip to completely power off if we enter runtime suspend and there is no jack detection active. This is helpful for systems where system suspend might remove the supplies to the CODEC, without informing us. Note the powering off is done in runtime suspend rather than system suspend, because we need to hold reset until the first time DCVDD is powered anyway (which would be in runtime resume), and we might as well save the extra power.
