ARM: initial Rockchip stuff for 4.3

Hi Olof, Kevin, Arnd,

The 3 patches add support for the rk3368 ARM64 soc from Rockchip. Patch 3/3 needs a dependency, namely

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git clk-rk3368

which Stephen Boyd declared stable.

The patches for rk3368 have been on the lists for 3 weeks now.

The two pull requests then add stuff for the 32bit Rockchip socs explained in the signed tags in them.

So if nothing stands out, please apply and pull.

Thanks
Heiko

The rk3368 is Rockchip's first ARM64 soc, build around 8 Cortex-A53 cores.

Enable building Rockchip support in the defconfig.

APplied, but based on earlier email with Will, we might need to deal with this conflicting with them enabling feature options. Should be manageable.

In terms of peripherals the rk3368 is quite similar to the rk3288, which makes it possible to have a lot basic components working in the first go. More to follow once I tracked down all the tiny differences that still exist in some parts.

With these dts files, the R88 board is able to boot from an attached usb device and most likely from its emmc too, if the emmc uses a standard partition table instead of Rockchip's own one - the emmc itself is detected correctly.

as mentioned in the cover letter, needed dependency (stable branch)
