ODROID N2+ fixes (#929)

Browse Source 
* Make sure to set board_rev for N2+ correctly

For some reason the code to set the environment did not make it into the
ODROID N2 board code. Fix the patch to correctly set board_rev for N2(+).
Also remove the w400 patch as it is no longer required.

* Use latest ODROID-N2+ patches

Use the queued patches (and fixes) for upstream ODROID-N2+ support.
This uses the clock settings from meson-g12b-a311d.dtsi running the
CPUs at the following clocks:
- 4xA73@2.2GHz
- 2xA53@1.8GHz

Subject: [PATCH 1/2] ARM: meson: isolate loading of socinfo
Move loading of socinfo into a separate function so the value can be
reused later.
