Version 1.2 enables voltage control for the CPU's regulator by using a GPIO line to toggle a MOSFET that can change the effective resistance value in the regulator's feedback network. This patch adds a common .dtsi file for this new revision, which includes the original common sunxi-bananapi-m2-plus.dtsi file, and adds the GPIO-controlled regulator and a cpu-supply reference. H3 and H5 variant dts files are added as well.
