ARM: SoC platform updates for v4.7

Browse source 
We get support for three new 32-bit SoC platforms this time. The amount
 of changes in arch/arm for any of them is miniscule, as all the
 interesting code is in device driver subsystems (irqchip, clk, pinctrl,
 ...) these days. I'm listing them here, as the addition of the Kconfig
 statement is the main relevant milestone for a new platform. In each
 case, some drivers are are shared with existing platforms, while
 other drivers are added for v4.7 as well, or come in a later release.
 
 - The Aspeed platform is probably the most interesting one, this is
   what most whitebox servers use as their baseboard management
   controller. We get support for the very common ast2400 and ast2500
   SoCs. The OpenBMC project focuses on this chip, and the LWN
   article about their ELC 2016 presentation at
   https://lwn.net/Articles/683320/ triggered the submission, but the
   code comes from IBM's OpenPOWER team rather than the team at
   Facebook. There are still a lot more drivers that need to get added
   over time, and I hope both teams can work together on that.
 
 - OXNAS is an old platform for Network Attached Storage devices
   from Oxford Semiconductor. There are models with ARM10 (!) and
   ARM11MPCore cores, but for now, we only support the original ARM9
   based versions.
   The product lineup was subsequently part of PLX, Avago and now the
   new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
   has some more information.
 
 - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
   cores and is related to the existing Realview / Versatile Express
   lineup, but without MMU. We now support various NOMMU platforms,
   so adding a new one is fairly straightforward.
   http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
   has detailed information about the platform.
 
 Other noteworthy updates:
 
 - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux
   are now maintaining the platform. This is an older ARM9 based
   platform from NXP (not Freescale), but it remains in use in embedded
   markets.
 
 - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both
   32-bit and 64-bit ARM, and started contributing some patches.
 
 - As is often the case, work on the OMAP platforms makes up the bulk of
   the actual SoC code changes in arch/arm, but there isn't a lot of
   that either.
