hwmon: (w83795) Exclude fan control feature by default

The fan control feature of the w83795 driver is insufficiently
reviewed and tested for public consumption at this time, so make it
optional and disabled by default. We will change the default when
review and testing is deemed sufficient. Ultimately the option will
go away.

           This driver can also be built as a module.  If so, the module
           will be called w83795.

+          fan control features will be included in the driver.

+          This part of the code wasn't carefully reviewed and tested yet,

+          Please also note that this option will create sysfs attribute
+          files which may change in the future, so you shouldn't rely
+          on them being stable.
