This isn't a device tree patch for WM8994, it's a patch for the
SMDK5420.

These names look wrong - they should reflect the names in the schematic
as they're for human comprehensibility.  This may just be a case of
dropping the -supply.

It would be helpful to also add a clock binding (I posted a binding
documentation update the other day, it's in my tree now) but it's not
essential and I suspect it needs some work on the clock driver side
still.
