This series is based on tip/master (commit 1912a07f8a)

SNP guests should only retrieve the AP Jump Table address from the
secrets page, not via a GHCB request as with SEV-ES guests. This series
reworks the handling accordingly, and fixes up some __init annotations
for some of the SEV routines touched by that rework.

v4:
 - Improve commit msg for patch 2 (Tom)

v3:
 - Address missing __init annotations (Boris)

v2:
 - add handling for memremap()/ioremap() failures (Boris)
 - don't mix function calls with declarations (Boris)
