The Apple M1 SoC has two mechanism for doing IPIs. The first method uses
the interrupt controller, the second method used implementation-specific
CPU registers. The M1 Pro/Max SoCs use a modified interrupt controller
that no longer provides the first method. So switch to the second method
in preparation for adding M1 Pro/Max support to OpenBSD. As a bonus this
mechanism seems to be faster (which may be why Apple calls these "fast"
IPIs).
