[PATCH] aarch64: Add tests that are failing intermittently

I've seen these failures on my local system, in our CI, and on a build
server that I sometimes
use for development/testing so if it's a configuration issue we're being
pretty consistent about
misconfiguration across some pretty different environments (docker,
bare-metal, VM, different
OSs, different QEMU versions). I've seen enough of the spintrcritical
tests fail sporadically on
QEMU to lump them all into this category. These are also tests that I
have seen behave badly
on ARMv7 QEMU on my local system (which doesn't rule out
misconfiguration, but it's another
data point).
As far as your worry about marking these indeterminate, they're only
being marked as such for
QEMU BSPs. The ZynqMP hardware BSP doesn't have these testing carve-outs
and runs all
these tests flawlessly.
These failures become much more common when there is otherwise load on
the system and a
lot of them disappear when you limit the tester to a single QEMU
instance at a time.
