[PATCH] hwmon: kill client name lm78-j 



Drop the separate client name for the LM78-J chip. This is really
only a later revision of the LM78, with almost no difference and
no difference the driver handles in any case.

This was the only client name that had a dash in it, and special care
had to be taken in libsensors because of it. As we plan to write a new
library soon, I'd like to get rid of this exception before we do.

As a nice side effect, it saves 876 bytes in lm78.ko.
