Current reset vector uses 0xffffffe0 as AP waking vector, and expects
GenFv generates code aligned on a 4k boundary which will jump to this
location. However, some issues are listed below
1. GenFV doesn't generate code as the comment expects, because GenFv
assumes no modifications are required to the VTF-0 'Volume Top File'.
2. Even if removing VFT0 signature and let GenFv to modify, Genfv is
hard-code using another flash address 0xffffffd0.
3. In the same patch series, AP waking vector code is removed from
GenFv, because no such usage anymore. The existing of first two issues
also approve the usage is not available for a long time.
Therefore, remove AP waking vector related code.

Some implementations may need to keep the initial Reset code to be
separated out from rest of the code.This request is to add padding at
lower 4K region below 4 GB which will result having only few jmp
instructions and data at that region.

Previously, we would build the page tables in
Tools/FixupForRawSection.py.
In order to let NASM build VTF0 from source during the EDK II build
process, we need to move this into the VTF0 NASM code.
