[PATCH 2/9] ARM: dts: sun9i: a80-optimus: Add node for AXP809's unused dc1sw regulator

[Chen-Yu Tsai]

The DC1SW output from the AXP809 is unused. Unused regulators should
still be listed so as to be considered to be fully constrained.

Fixes: aa4a27bc819e ("ARM: dts: sun9i: a80-optimus: Add AXP809 PMIC
                      device node and regulators")
