thermal: Nct1008 driver refactoring

In order to implement fix for the Bug 1415692, the NCT1008 driver
had to be cleaned up and refactored, to support not only External,
but also Local sensor. This improvement aims to introduce more
generic structures and functions, to be used by the fix in the next
commit.
