amdfwtool: Correct the PSP2 directory layout

PSP2 is for Combo BIOS, which is the idea that one image supports 2
    kinds of APU.

The PSP2 feature is for the future, not for current products.
    The newest document about PSP2 is not available. I made it from the
    draft code I made when I was in AMD.
