vc/amd/pi/00670F00/binaryPI: cache the AGESA dispatcher 

Instead of repeatedly walking cbfs for the AGESA blob and parsing it
cache the resulting dispatcher value. There's only one dispatcher table
so use it. The resulting change is that this work is done one time per
stage.

BUG=b:70401101
TEST=Booted and noted only one lookup per stage.
