The current kernel code assumes big endian and parses RTAS events all
wrong. The most visible effect is that we cannot honor EPOW events,
meaning, for example, we cannot shut down a guest properly from the
hypervisor.
This patch fixes that.

Thanks Kevin. Your patch works normal. :)
I still have some confused. I think when __do_softirq always get a interrupt,
the hard stack will be run out, isn't it?

This patch improves fsl_sai_isr() in these ways:
1, Add comment for mask fetching code.
2, Return IRQ_NONE if the IRQ is not for the device.
3, Use regmap_write() instead of regmap_update_bits().
