ARM: dts: sun9i: cubieboard4: Add AXP806 PMIC device node and regulators
The AXP806 PMIC is the secondary 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>
