hwmon: (w83627ehf) Convert register arrays to 16 bit, and convert access to pointers 

For newer chips, several registers are banked and thus need to be 16 bit.
Also, register addresses change.

To prepare for those chips, convert affected register arrays to 16 bit,
and change access to those registers to array pointers in struct w83627ehf_data.
