pd: refactor pd policy layer request voltage functions
Remove common code across all PD policy layers to select the requested
voltage and build a Request Data Object (RDO).
BUG=none
BRANCH=samus
TEST=Load onto samus and connect zinger. Make sure we request the right
voltage (first 5V, then after initial contract is made, 20V). Make
sure input current limit is set appropriately by checking limit on EC
console using charger command.
