hwmon: (k10temp) Define a helper function to read CCD temperature

Browse source

The CCD temperature register is read in two places. These reads are done
using an AMD SMN access, and a number of parameters are needed for the
operation.

Move the SMN access and parameter gathering into a helper function in order to
simplify the code flow. This also has a benefit of centralizing the hardware
register access in a single place in case fixes or special decoding is required.
