In 64-bit mode, kernel just clears the irq soft-enable flag
in struct paca_struct to disable external irqs. But, in
the case of suspend, irqs should be disabled by hardware.
Therefore, hook a function to ppc_md.suspend_disable_irqs
to really disable irqs.

64-bit modes can work. Used some callback functions implemented in RCPM
driver.
