This is likely going to cause a circular dependency, because the RSB
interface that is used to talk to the PMIC is also on the PL pins.
(How does FreeBSD deal with this?)
Instead, just add a comment describing what is really used, and set
the regulator to always-on, which should already be the case.

Indeed that cause a Linux kernel to not boot at all.

We don't deal with vcc-X-supply until later in the boot, this is not
ideal but better than not dealing with them.

Ok will do,
