Drop commit 22475bcc ("regulator: userspace-consumer: Add regulator
event support") since Zev Weiss points out that it leaks the constants
we use for notifications out as ABI which isn't ideal, we should have
something more abstracted there.  There's a definite need for this
feature but it needs some more work on the interface.
