hwmon: (applesmc) Cache fan positions during register initialization

Browse source

To support the read_string callback for fan labels in the modern HWMON
API, load and cache the fan position names in smcreg.fan_positions
during register initialization.

Pre-pad fallback labels with four spaces to match the "+ 4" pointer
arithmetic offset used by all fan labels in the read_string callback.
