ARM: SoC: platform support for v4.2

Our SoC branch usually contains expanded support for new SoCs and
other core platform code. Some highlights from this round:

- sunxi: SMP support for A23 SoC
- socpga: big-endian support
- pxa: conversion to common clock framework
- bcm: SMP support for BCM63138
- imx: support new I.MX7D SoC
- zte: basic support for ZX296702 SoC

 Conflicts:
	arch/arm/mach-socfpga/core.h

Trivial remove/remove conflict with our cleanup branch.
Resolution: remove both sides

STM32 ARM Linux Overview
========================
Introduction
------------
The STMicroelectronics family of Cortex-M based MCUs are supported by the
'STM32' platform of ARM Linux. Currently only the STM32F429 is supported.
Configuration
-------------
A generic configuration is provided for STM32 family, and can be used as the
default by
make stm32_defconfig
Layout
------
All the files for multiple machine families are located in the platform code
contained in arch/arm/mach-stm32
There is a generic board board-dt.c in the mach folder which support
Flattened Device Tree, which means, it works with any compatible board with
Device Trees.

For the Vybrid SoC familiy all variants with DDR controller are supported,
which is the VF5xx and VF6xx series. Out of historical reasons, in most
places the kernel uses vf610 to refer to the whole familiy.
The compatible string "fsl,vf610m4" is used for the secondary Cortex-M4
core support.
