[PATCH] rtc: ds1307: simplify hwmon config

[Heiner Kallweit]

We don't have to define an extra config symbol, IS_REACHABLE does
what we need. And having this config symbol just to save the few
bytes of hwmon support on non-DS3231 chips isn't worth it IMO
(especially as the symbol is set per default).
