Merge tag 'arm-soc/for-4.8/soc-arm64-part2' of http://github.com/Broadcom/stblinux into next/arm64

Merge "Broadcom ARM64-based SoC changes for 4.8 second part" from Florian Fainelli:

- Eric updates the bcm2836 interrupt controller driver not to rely on ARM/Linux specific functions
  in preparation for using it on ARM64

- Eric also adds a Kconfig entry for the BCM2835 Raspberry Pi family in the ARM64 Kconfig.platforms
  file

- Eric cherry picked a patch from Alexander Graf with Acks from ARM64 maintainers to support different
  DMA and bus offsets, required for the Raspberry Pi 3 SoC

* tag 'arm-soc/for-4.8/soc-arm64-part2' of http://github.com/Broadcom/stblinux:
  arm64: Add platform selection for BCM2835.
  arm64: Allow for different DMA and CPU bus offsets
  irqchip: bcm2835: Avoid arch/arm-specific handle_IRQ
