hwmon: (mc13xxx-adc) make name buffer larger

This is doesn't change how the code works, it's just a thing to make the static checkers happy. We transfer a 12 character string from a 20 character buffer to a 10 character buffer using snprintf(). The static checkers complain that that lops off the last couple characters.

The static checkers are right, but it turns out we don't care because later on we truncate the name at the '-' character. Oh well, let's change it so they don't complain.
