rtc: ac100: support clock-output-names in device tree binding
The ac100 device tree binding specifies the usage of clock-output-names to specify the names of its 3 clock outputs. This is needed for orphan clock resolution, when the ac100 is probed much later than any clocks that consume any of its outputs. This wasn't supported by the driver. Add support for this.
