acpi_wakeup_address is used on x86 as the address bios jumps into
when machine wakes up from suspend. As arm64 does not have such a
bios this mechanism will be provided by other means. But the define
is still required inside the acpi core.

Introduce a null stub for acpi_suspend_lowlevel as this is also
required by core. This will be filled in when standards are
defined for arm64 ACPI global power states.

Do we actually plan to use these on arm64? I'm worried most of these
don't make sense on arm64 (the aim is to use PSCI). Is it possible to
refactor the core code so that we don't have to define dummy macros or
variables just to be able to build the kernel?
