Add support for sample rates other than 44100Khz on raumfeld audio devices. Force the codec's supported sample rates as the table of supported rates which is calculated at run-time does not suffice: if we call snd_soc_dai_set_sysclk() at stream startup, half of the possible rates are missing.

I'm not massively enthusiastic about this - I'd much rather be able to give the CODEC a hook to let it know what MCLK rates it can have and a callback to update them. It's a perfect case for the clock API but of course we can't use that off-SoC :/

This is how I was planning on doing it for the P1022DS.
