One die is the actual PMIC. The other is an AC100 codec / RTC combo chip. This patch enables the RSB controller and adds a device node for the PMIC die to the Cubietruck Plus device tree. Since the AXP813 and AXP818 are virtually identical, this patch uses the compatible string for the former as a fallback.
