Topic branch for adding Exynos 5410 Odroid XU board for v4.8.

This brings support for Hardkernel's Odroid XU board.  It was the first
design with big.LITTLE SoC from Samsung: Exynos5410.  The board is not
very popular.  Newer XU3 and XU4 got more attention.

1. Exynos5410 octa-core (A15+A7, however as of now only one cluster is
   enabled),
2. 2 GB DDR3 RAM,
3. PowerVR SGX544MP3 GPU (not enabled in DTS),
4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4,
5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of
   revisions though),
6. eMMC 4.5 and microSD slots.
