[PATCH v3 0/2] hwmon: (nct6775) Support access via Asus WMI

Support accessing the NCT677x via Asus WMI functions.

On mainboards that support this way of accessing the chip,
the driver will usually not work without this option since
in these mainboards, ACPI will mark the I/O port as used.

@Andy Shevchenko, I have left type of sioreg, in other places
sioreg has same integer type, should I change all occurrences
of usage?
@Guenter Roeck, I have left nct6775_*_set_back() call without
changes as its always called from platform specific callbacks.

Could you please review?
