sunxi: DT: H3: update board .dts files from Linux

Update the .dts file for the various boards with an Allwinner H3 SoC.
This is as of v4.18-rc3, exactly Linux commit:
commit 721afaa2aeb860067decdddadc84ed16f42f2048 (HEAD)
Merge: 7c00e8ae041b 87815dda5593
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Jun 11 17:57:38 2018 -0700

    Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

This also includes the OrangePi Zero .dts, which technically has an
Allwinner H2+ SoC.
