Subject: [PATCH 2/3] riscv: dts: allwinner: d1s-t113: Add system LDOs

From: Chen-Yu Tsai <wens@...e.org>

Now that the bindings for the system LDOs have been merged, the nodes
for the system LDOs can be added. These are used on the ClockworkPi.

This was originally part of Samuel's D1 device tree series [1], but was
dropped in v5 as the regulator bindings weren't merged at the time.
