ARM: dts: sun9i: cubieboard4: Add AXP809 PMIC device node and regulators
The AXP809 PMIC is the primary PMIC. It provides various supply voltages for the SoC and other peripherals. The PMIC's interrupt line is connected to NMI pin of the SoC. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
