firmware: stratix10-svc: add async HWMON read commands and register socfpga-hwmon device
Add asynchronous Stratix 10 service layer support for hardware monitor
temperature and voltage read commands in stratix10_svc_async_send() and
stratix10_svc_async_prepare_response().
Register a socfpga-hwmon platform device from the service layer driver
when hardware monitor support is enabled, similar to the RSU device.
