ARM: multi_v7_defconfig: Switch AXP20x driver from module to built-in

The AXP20X regulator support is currently built as a module, which means
it's not available until the root fs has been mounted, but the boot loader
might not have enabled the required regulators, so build their drivers
into the kernel.
