In order to support the SMP feature of the Oxford Semiconductor OX820 SoC,
add the necessary code to handle the wake-up, hotplug and cpu entry.

The OX820 has an ARM11MPCORE cluster with 2 cores and has proper hardware
support for secondary core booting.

Changes since v1 at http://lkml.kernel.org/r/20161017084303.20078-1-narmstrong@baylibre.com
 - Remove useless holding pen loops and spinlock in boot_secondary
