sunxi: Sync dts files with the upstream kernel

Sync dts files with the upstream kernel including
changes queued for 4.6:

https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?h=sunxi/dt-for-4.6

Note this adds a number of new unused board dts files. I've asked the
authors of the kernel commits adding these to submit a matching defconfig
to u-boot.
