Merge branch 'axxia/soc' into next/soc

Patches from Anders Berg applied individually:

Here is version 4 of platform support for AXM5516 SoC.

The clk driver is now applied to clk-next. The rest should be ready for
arm-soc. Haven't got any response from the power/reset maintainers... I hope
this driver can be taken via arm-soc as well.

The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an
L2 cache, and the clusters are connected to each other via a CCN-504 cache
coherent interconnect.

This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located
above 4GB in the memory map.

* axxia/soc:
  ARM: dts: axxia: Add reset controller
  power: reset: Add Axxia system reset driver
  ARM: axxia: Adding defconfig for AXM55xx
  ARM: dts: Device tree for AXM55xx.
  ARM: Add platform support for LSI AXM55xx SoC
