For the actual DTS files, I could add a wilink.dtsi with enumerations
for these values so they could be used in the node definitions. But I'm
not sure it's going to be that valuable in the end.
The way GPIO HIGH was defined might help to provide guidance I think :)

Where? As far as I can see, the GPIO flags are defined in a bitmap.

include/dt-bindings/gpio/gpio.h
And corresponding kernel header:
include/linux/of_gpio.h

just a hint. not saying frequencies were defined in header. for systems that define frequencies - example cpufreq OPPs, clock node usage, we do not use indexing to frequency, instead, that is the responsibility of driver to convert frequency back to required index.
git grep frequency Documentation/devicetree/bindings gives you how the precedence looks like.

Personally, if given a choice, I'd go with actual frequencies rather than indexes.
