Hmm... that's true. But we already have a way to deal with exactly this
situation for regulators. There's a property called regulator-boot-on
which a bootloader should set whet it has enabled a given regulator. It
can of course also be set statically in a DTS if it's know upfront that
a bootloader will always enable it. Perhaps what we need is a similar
property for clocks so that the clock framework will not inadvertently
turn off a clock that's still being used.

Except that such a property won't work either. Regulators with
regulator-boot-on will still be disabled if there's no one to claim
it. Just like what happens currently for the clocks.
