ASoC: cs42l73: Fix Output [X|A|V]SP_SCLK Sourcing Mode setting for master mode

For master mode, set Output [X|A|V]SP_SCLK Sourcing Mode to MCLK Mode.

---
Hi Brian,
I think current code of setting priv->config[id].spc for master mode is wrong:
priv->config[id].spc &= MCK_SCLK_64FS; will set priv->config[id].spc to be 0.

I don't have this hardware, I'd appreciate you can review and test this patch.

Regards,
Axel

Hey Axel,

Thanks for the catch. Yes, for most normal slave operations where sclk = mclk you would set it the way you have it.

There is however another case where the SCLK = PREMCLK that puts constraints on the supported rates for the MCLK. Your fix catches the majority of uses for Codec slave mode though.

Applied, thanks.
