x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUME
At present this enables a few arch-specific members of the global_data
struct which are otherwise not part of the struct. As a result we have to
use #ifdef in various places.
The cost of always having these in the struct is small. Adjust things so
that we can use compile-time code instead of #ifdefs.
