[PATCH RFT 3/3] regulator: wm831x-ldo: Add dummy set_suspend_[enable|disable] callbacks implementation

[Axel Lin <axel.lin@gmail.com>]

Without the implementation of set_suspend_enable and set_suspend_disable callbacks,
the regulator core won't call set_suspend_voltage.

Thus add dummy implementation for set_suspend_[enable|disable] callbacks.
