sunxi: Sync dts files with upstream kernel

Sync dts files with the current (Aug 18th 2016) state of Maxime's
linux/sunxi/for-next repo.

Note this commit also updates configs/MSI_Primo81_defconfig,
adding: "# CONFIG_REQUIRE_SERIAL_CONSOLE is not set", this is necessary
because the tablet does not have a reachable uart so the dts sync
drops its serial0 alias.
