sensors-detect: Fix the driver for Nuvoton W83677HG-I

Originally, support for the Nuvoton W83677HG-I and derivatives was first added to the w83627ehf driver, so that's the driver recommended by sensors-detect. Later, support for the same device was added to the nct6775 driver. In kernel v5.6, support was removed from the w83627ehf driver to get rid of the duplicate code.

So sensors-detect should now point users of this device to the nct6775 driver. We can't do that for very old kernels though, as this driver did not exist back then. I chose v3.10 for the cut-over, as this is when support for the Nuvoton W83677HG-I was finalized in the nct6775 driver, at least according to git log.
