mfd: wm8994: Don't use system PM operations
For realistic systems the power management is controlled entirely via runtime PM - if the device is not runtime suspended then the suspend will abort without doing anything as functionality such as accessory detection or audio bypass will require the device to be enabled while if the device is runtime suspended it is already in the lowest power state. This means that system suspend is redundant and can be removed which avoids issues with attempting to double disable the regulators.
