util/superiotool: Register fix for Fintek F81865F/F-I

Datasheet: http://www.fintek.com.tw/files/productfiles/F81865_V028P.pdf

There is a multi-function select register listed as 0x2a-1 and 0x2a-2.
These are the original names in the datasheet, but superiotool will
display register 0x29 and 0x28 and their values.
This patch renames them both to 0x2a and shows both of the default values
for them. They are both 0x00, so one of them could be dropped though.
