If we only need to "combo" two PSP directories into one image,
we can put first address in romsig 0x10 and second one in
romsig 0x14.
If we really need to put three, the 0x14 is the combo directory
which points to multiple level-2 PSP directories.
I guess that two PSP can also use combo directory, with only
one level-2 directory. But nobody seems to do that.

I didn't go back through the development guide for this.
But based on test, if the empty entry is filled as 0xFFFFFFFF,
instead of 0, the USB3 port can not be used.
Leave the entries of PSP and PSP2 as 0xFFFFFFFF to be compliant
with the case before the amdfwtool is used.

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.
