Use task_stack_page instead of p->stack to get stack. Follow the coding
convention style. Also for init_stack, the same with other archs.

csky: CPU-hotplug supported for SMP2018-12-31T15:03:53ZGuo Renren_guo@c-sky.com2018-12-19T11:56:14Zurn:sha1:859e5f45cbb33fe5d591a8e429667f0b7d4f4be8
This is a simple implement of CPU-hotplug for power saving. CPU use
wait instruction to enter power saving mode and waiting for IPI wakeup
signal.

csky: Don't leak device tree node reference2018-12-30T12:25:39ZYangtao Litiny.windzz@gmail.com2018-12-27T17:45:51Zurn:sha1:398539dd69341f8e3b87b8fea9355c7edfb6d99a
of_find_node_by_type() acquires a reference to the node returned by it
and that reference needs to be dropped by its caller. setup_smp()
doesn't do that, so fix it by converting to for_each_of_cpu_node().
