amd/pi/hudson: Reduce amdfw space requirement

Change the current implementation so that multiple PSP directory
structures are not included, saving 448 KB.

AMD created a mechanism so that multiple generations of APUs, in
identical packages, may be supportable in one BIOS image.  The PSP
identifies the correct directory table by checking one of two
pointers in the Embedded Firmware structure.  Coreboot doesn't
implement this capability, however it has been constructing
amdfw.rom with two identical directory tables and two copies of
each PSP blob.

Tested on Bettong (Merlin Falcon / Carrizo) and Jadeite (Stoney).
