Make hwmon work with double or int64 interface

Deduce type based on interface using decltype
and if it is double apply scale to the value.

Tested-by: Noticed that on dbus using busctl and debug
server that doubles were produced and scaled.

Also verifed that hwmon still produced int64_t values when
building with current phosphor-dbus-interfaces.
