Most AXP PMICs feature a "startup source" register, which keeps information about how the PMIC started operation. Bit 0 in there means it has been started by "plugging in the power cable". Define a symbol in each PMIC's header file to be able to use that register and bit later on. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
