hwmon: (nct6775) Add support for NCT6792D 

NCT6792D is similar to NCT6791D. Only beep control and temperature
monitoring registers are different.

If you say yes here you get support for the hardware monitoring
functionality of the Nuvoton NCT6106D, NCT6775F, NCT6776F, NCT6779D,
NCT6791D and compatible Super-I/O chips. This driver replaces the
w83627ehf driver for NCT6775F and NCT6776F.
NCT6791D, NCT6792D and compatible Super-I/O chips. This driver
replaces the w83627ehf driver for NCT6775F and NCT6776F.
This driver can also be built as a module. If so, the module
will be called nct6775.
