ARM: SoC devicetree updates for 3.16

As with previous release, this continues to be among the largest branches
we merge, with lots of new contents.

New things for this release are among other things:

- DTSI contents for the new SoCs supported in 3.16 (see SoC pull request)
- Qualcomm APQ8064 and APQ8084 SoCs and eval boards
- Nvidia Jetson TK1 development board (Tegra T124-based)

Two new SoCs that didn't need enough new platform code to stand out
enough for me to notice when writing the SoC tag, but that adds new DT
contents are:

- TI DRA72
- Marvell Berlin 2Q
