mips/octeon/smp: Convert to hotplug state machine
Install the callbacks via the state machine. [ tglx: Renamed the state to MIPS_SOC_PREPARE so it can be reused by other SOCs ] Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Acked-by: Ralf Baechle <ralf@linux-mips.org> Cc: linux-mips@linux-mips.org Cc: Peter Zijlstra <peterz@infradead.org> Cc: rt@linutronix.de Link: http://lkml.kernel.org/r/20160906170457.32393-16-bigeasy@linutronix.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
