hwmon: (w83795) Use 2D arrays for many device attributes

Use 2D arrays for in, fan, temp and dts device attributes. Using
linear arrays is too risky as we have to skip some groups depending
on the device model and configuration. Adding or removing an
attribute would let the driver build silently but then it would crash
at runtime. With 2D arrays, the consistency checking happens at build
time, which is much safer.
