psci_attach is way too late to provide the intended semantics for
psci_present. psci calls can be made immediately after psci_init(),
called way earlier at SI_SUB_CPU + SI_ORDER_FIRST, and we need it to
be valid as early as we can possibly call a psci function.
This fixes booting RPi3+4 with the in-review spintable patch;
rpi3-psci-monitor patches the FDT to add a PSCI node, but it doesn't
patch each cpus' enable-method. Because of this, we would stall the
boot while enabling CPU 1 as we saw a valid looking enable-method and
"no" functional PSCI and attempted to use the spintable rather than
simply not starting secondary APs.
