Subject: [PATCH 1/3] x86/sev: Move the internal header

From: "Borislav Petkov (AMD)" <bp@...en8.de>

Move the internal header out of the usual include/asm/ include path
because having an "internal" header there doesn't really make it so
- quite the opposite.

So move where it belongs and make it really internal.

No functional changes.
