ARM: oxnas: remove CPU hotplug implementation
The CPU hotplug implementation on this platform is cargo-culted from
the plat-versatile implementation, and is buggy. Once a CPU hits the
"low power" loop, it will wait for pen_release to be set to the CPU
number to wake up again - but nothing in this implementation does that.
So, once a CPU has entered cpu_die() it will never, ever leave.
Remove this useless cargo-culted implementation.
