[PATCH] pmac: don't add °C suffix in sys for adt746x driver

The adt746x driver currently adds a "°C" suffix to temperatures exposed via
sysfs, and I don't like that.  First, we all agree that any other unit here
makes no sense (do we ?  do we ?  yes of course :) and I don't like having
anything but numbers in there, and finally it's more consistent with what
the g5 driver does.

And finally, the _REAL_ reason is that this is not a low ASCII character
and so has nothing to do in the kernel sources or in /sys :)

Unfortunately, generating a patch here is nasty because of that (my mailer
is rightfully complaining about the non-ASCII char on text import) so you
might have to apply by hand...
