amdfwtool: Fix some PSP2 issues 

1. Change the function which integrated one firmware, to the function
   which pushes the whole group. Use fw_table as a parameter instead
   of using the global table name.
2. Let PSP2 and PSP1 not dependent on the other. It turns out PSP2
   can exist without PSP1. For some APU, the PSP directory has to be
   put in PSP2 field (ROMSIG 0x14).
3. Reserve 32 more bytes in PSP2 header. It is defined by spec. It
   is tested, and it is true.

These above changes are overlapping, hard to split them. Sorry.
