This adds U-Boot configuration for LEGO MINDSTORMS EV3. U-Boot has
had support for LEGO MINDSTORMS EV3 since v2016.05.

Bump kernel revision used by lego_ev3_defconfig to the latest tag from
ev3dev, as suggested by Peter. This is a 4.4 series kernel, which has the
added benefit of not necessitating a specific gcc to boot.
We need a patch to create an empty drivers/lego/Kconfig file for the build
to succeed though, as the ev3dev kernel normally expects a drivers tree to
be checked out there.

For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
- a standard upstream version string vX.Y.Z
- a non-standard version string, but still containg the standard X.Y.Z
Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.
There are a few cases were there was a mismatch:
- microzed: uses a 3.18 kernel, but 3.8 headers; fixed.
- xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
- zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.

Add initial support for the Lego Mindstorms EV3 programmable brick.
The Lego Mindstorms EV3 brick comprises a Texas Instruments AM1808 SoC, with
an ARM 926EJ-S main processor running at 300 MHz.

This configuration uses the Linux kernel of the ev3dev project.

More info is available in the board/lego/ev3/readme.txt file, shamelessly
documented in the same way as the SoCkit folks did.
[Peter: lock kernel headers to match]
