ARM: SMP: support Broadcom mobile SoCs

This series adds SMP support for two Broadcom mobile SoC families.
It uses CPU_METHOD_OF_DECLARE() so that SMP operations are assigned
using device tree rather than adding it to a machine definition in a
board file.

The enable method starts a secondary core by writing to a register
monitored by CPUs spinning in a ROM-based holding pen loop.  The
address of this register is recorded as a property in the "cpus"
node of the device tree.

Notes:
    - This series previously included the binding as its first patch.  That
      has now been posted separately to facilitate and focus review.
    - This series is based on v3.16-rc1, plus two recently-posted patches:
