mfd: wl1273-core: Remove the header

The wl1273 FM radio is on Arnd's unused driver list:

https://lore.kernel.org/lkml/a15bb180-401d-49ad-a212-0c81d613fbc8@app.fastmail.com/

Other patches have removed the core, the ASoC code and the Radio code.
With all those in, remove the header.

Also, tidy the ref in the docs.
