amdfwtool: Postpone the usage of PSP combo directory

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.
