The idea is that by putting this into debugfs we have a single source of
information to use in tests.

Now if in addition to merely testing the frequencies you want to make
sure the driver has a consistent representation of what's in device tree
we could always write another test that reads the device tree nodes and
compares them to the list of supported rates from debugfs.
