AGESA: Move romstage-ramstage splitline
In AGESA specification AmdInitEnv() is to be called once
host memory allocator has started. In coreboot context this
could mean either availability of CBMEM or malloc heap.
As for AmdS3LateRestore(), there is no requirement to have
it run as part of the romstage either.
