I have now created v5 here with the latest code appearing in SecurityPkg 
again: 
https://github.com/stefanberger/edk2/commits/stefanberger/ovmf_disable_platform_hierarchy.v5

I can probably post that pretty quickly but I'll be out for a while. If 
it's urgent, someone else can pick it it up from there. I tested it on 
QEMU for x86 and aarch64 and test-compiled on various platforms that I 
touched (some didn't compile for me before the changes).

What I wasn't sure about is whether edk2-platforms is a 'holding area' 
for code to be imported ideally 1:1 into edk2. So I ended up making 
those changes already in v1 to cut out a dependency. If what I have in 
v5 (or also v4) is sufficient for general consumption, then let's put it 
into SecurityPkg.
