I don't understand this.  Why is this called _no_delay() and why don't
we want to delay when applying constraints?  We don't want to ever be in
a position where we think a supply is enabled but it has in fact not
finished ramping, and of course enable() may in fact be blocking anyway.

The use of the common code to do enable is good fix but this just seems
odd.
