ARM: TC2: reset CPUs spuriously woken up on cluster power up
On TC2, all CPUs in a cluster are woken up when an IRQ event triggers for a
CPU in a cluster in shutdown state.
This patch puts spuriously woken CPUs back in reset by checking the
pending IRQ status in the SPC wake-up interrupt status register; if the
CPU has no pending IRQ routed to it, the core reexecutes wfi and it is put
in reset by FW straight away.
