It's so that if you have multiple logical users within the device (eg,
an interrupt handler and code for normal operation) they can work
independently of each other.  You could also request the regulator
multiple times but that's often not idiomatic.

Originally we didn't actually refcount within the individual consumers
at all and only refcounted on the underlying regulator, the per consumer
reference count is mainly there for debugging purposes.
