superio/fintek/f71869ad: Configure multi-func reg in devicetree
Facilitate for the configuration of so called "Multi-function Select Registers" with devicetree.cb in ramstage. Make use of this new functionality in, mainboard/jetway/nf81-t56n-lf to correctly configure the Fintek's multiplexed GPIO pins to be in AMD TSI mode. This allows the Fintek to correctly talk to the Southbridge over the SMBus for CPU temperature data as to control fans and so on.
