acpi: Move MCFG implementation to common lib
MCFG tables are used on multiple arches. Move to common ACPI lib. Cc: Simon Glass <sjg@chromium.org> Signed-off-by: Moritz Fischer <moritzf@google.com> Reviewed-by: Simon Glass <sjg@chromium.org> Use sizeof(*mcfg) instead of sizeof(*header) Signed-off-by: Simon Glass <sjg@chromium.org>
