I didn't mean to change the nodename, but rather aliases.
BTW nodes should be sorted by nodename (placed at the top).

It is not an independent network. 5V_BOOST and 5V_OUT are on the same
VOUT, only separated by a diode. The device tree describes the hardware.
5V_OUT is not a regulator, it has no enable control, so treating it as
a standalone regulator is incorrect.

Adding a fake regulator is just a waste of startup time.
