hwmon/w83627ehf: Add error messages for two error cases
If the Super-I/O device is disabled, it is likely the BIOS has a good
reason for leaving it disabled, so give a warning when enabling it --
it's not likely to be wired correctly or be able to give good data.
Also, if the Super-I/O device is configured with an address of 0, the
driver refuses to initialize it.
