This updates Linux kernel for Synopsys ARC HS38 VDK so it matches real
platform and while at it bump kernel version to the latest.
Main changes:
* Linux kernel v4.9.6 (latest in 4.9.x series in buildroot)
* Add support of MMC controller which is used for rootfs
* Add support of UIO which is used to communicate with EVSS
Now with this update image built by vanilla Buildroot VDK has
working UART, MMC, LCD, Ethernet, UIO etc.
And while at it we rename defconfing so it:
1) Doesn't mention SMP any more - that's the only option anyways now
2) Matches common naming scheme: vendor_arch_platform

The Virtualizer Development Kit (VDK) Family for ARM Cortex Products
consists of a set of virtual prototypes that provide a virtualizer for
the ARM core variants. The VDK is a standalone package that runs on an
host computer.
[Thomas: drop the following options, which as noted by Arnout, are not
needed:
- BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM=y
- BR2_LINUX_KERNEL_IMAGE_TARGET_NAME="Image"
- BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y.]

Linux kernel 4.2 was finally released, so bumping from 4.2-rc5 to
final release.
Updating Linux headers to 4.2 branch since they are introduced in
Buildroot as well already.
Also adding 1 back-ported patch that makes SD/MMC cards usable on AXS
boards. This patch will be a part of 4.3 (already in linux-next) and
hopefully will make its way in 4.2.1.
Once that patch appears in 4.2.x it can be removed from here.

The AXS10x Platform consists of a DesignWare AXC001 CPU
Card (with ARC 770D core) in case of AXS101 or AXC003 CPU Card
(typically with ARC HS38 core) in case of AXS103 mounted on an
ARC Software Development Platform Mainboard with DesignWare peripherals:
* SD/MMC contoller
* Gigabit network contoller
* Serial ports (8250-compatible)
* USB 2.0
* SPI
* I2C
It also houses HDMI output for external monitor connection.
For stand-alone usage of the board (with only keyboard, mouse and montor
attached) kernel console and getty made available on tty0 as well as on
serial port (ttyS3).
Note there're 2 prerequisites:
[1] u-boot: 2015.07 - fix creation of .config
http://patchwork.ozlabs.org/patch/502558/
[2] binutils: fix buildng of Linux kernel for ARCv2 ISA
