ARM: SoC support for Tegra platforms for v4.5

Browse source 
Here's a single-SoC topic branch that we've staged separately. Mainly
 because it was hard to sort the branch contents in a way that fit our
 existing branches due to some refactorings.
 
 The code has been in -next for quite a while, but we staged it in arm-soc
 a bit late, which is why we've kept it separate from the other updates
 and are sending it separately here.

Enable support for the NVIDIA Tegra210 SoC. Also known as Tegra X1,
the Tegra210 has four Cortex-A57 cores paired with four Cortex-A53
cores in a switched configuration. It features a GPU of the Maxwell
architecture with support for DX11, SM4, OpenGL 4.5, OpenGL ES 3.1
and providing 256 CUDA cores. It supports hardware-accelerated en-
and decoding of various video standards including H.265, H.264 and
VP8 at 4K resolution and up to 60 fps.
Besides the multimedia features it also comes with a variety of I/O
controllers, such as GPIO, I2C, SPI, SDHCI, PCIe, SATA and XHCI, to
name only a few.
