Merge tag 'arm-soc/for-4.3/soc' of http://github.com/broadcom/stblinux into next/cleanup

Merge "Broadcom SoC changes for 4.3 (part 1)" from Florian Fainelli:

This pull request contains two fixes for the Broadcom BCM63xx SMP code:

- Sudeep removes an invalid use of cpu_logical_map() which turned to be a no-op
  since we always boot from physical CPU 0 = logical CPU 0

- Florian removes the custom secondary_startup function and replaces it with
  the generic one
