hdata: Enable SPIRA-H
Update the SPIRA-H pointer in the NACA so that the FSP can build and pass
the SPIRA-S structure to OPAL instead of the legacy SPIRA. Older systems
(which does not support SPIRA-H) ignores SPIRA-H pointer and continue to
pass legacy SPIRA.
"spira" is a global structure and referred everywhere inside hdata dir. Once
we enable SPIRA-H we get data in SPIRA-S area, not in legacy spira. Hence
fixup spira structure, so that we don't break building device tree.
