sunxi: Add defconfig and dts file for the Orange Pi PC Plus SBC

There is a new Orange Pi PC *Plus* version available now,
this is an extended version of the regular Orange Pi PC
with sdio wifi and an eMMC.

The upstream kernel devs have decided that they want a separate
dts for the PC Plus rather then sharing a single dts between the
regular PC and the PC Plus. So add a new orangepi_pc_plus_defconfig
to match.

The added dts file matches the one submitted to the upstream kernel.
