ARM: dts: sun8i: a83t: bananapi-m3: Add AXP813 regulator nodes
This patch adds device nodes for all the regulators of the AXP813 PMIC. Sunxi common regulators are removed, and USB VBUS regulators are added. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
