x86/sev: Add defines for GHCB version 2 MSR protocol requests
Add the necessary defines for supporting the GHCB version 2 protocol.
This includes defines for:
- MSR-based AP hlt request/response
- Hypervisor Feature request/response
This is the bare minimum of requests that need to be supported by a GHCB
version 2 implementation. There are more requests in the specification,
but those depend on Secure Nested Paging support being available.
These defines are shared between SEV host and guest support.
[ bp: Fold in https://lkml.kernel.org/r/20210622144825.27588-2-joro@8bytes.org too.
Simplify the brewing macro maze into readability. ]
