Moving acpi_early_init() after efi_enter_virtual_mode() will probably work. I
can't think of anything that will break necessarily, I would just try it and
see. The benefit is doing it before for BGRT is that we can free the
EfiBootServices memory a little bit earlier on boot.

But it's not at all clear to me what the root problem is here and whether a
straight up revert is just papering over a problem.
