x86/sev: Move early startup code into .head.text section
commit 428080c9b19bfda37c478cd626dbd3851db1aff9 upstream.
In preparation for implementing rigorous build time checks to enforce
that only code that can support it will be called from the early 1:1
mapping of memory, move SEV init code that is called in this manner to
the .head.text section.
