This adds support in X-Powers AXP20X and AXP22X battery driver for a fixed battery in DT. It will take the minimum supported voltage by the battery as defined in the battery DT node and set the V_OFF register to this value, telling the system to shut down if the supplied power is below this value.

This is not in -next. It would help if you mention any requisite patches. ChenYu
