Merge tag 'arm-soc/for-4.13/drivers' of http://github.com/Broadcom/stblinux into...

This pull request contains Broadcom ARM/ARM64 SoCs specific driver changes for
4.13, please pull the following:

- Doug adds support for the latest generation GISB bus arbiter (v7), he starts by
  fixing two issues in how registers are written, and how 64-bit addresses are captured
  and then he simplifies the error interception by using notifiers, which allows him
  to add support for ARM64

- Markus updates the SOC_BRCMSTB Kconfig depends to cover ARM64 and BMIPS_GENERIC
  systems where this code is now also used
