x86, nx: Mark the ACPI resume trampoline code as +x
We reserve lowmem for the things that need it, like the ACPI
wakeup code, way early to guarantee availability. This happens
before we set up the proper pagetables, so set_memory_x() has no
effect.
Until we have a better solution, use an initcall to mark the
wakeup code executable.
