Subject: [PATCH] ASoC: dt-bindings: rockchip: i2s-tdm: fix rockchip,cru requirement

The behaviour described in the bindings is exactly the opposite
of what it should be, so this patch fixes the description and
adjusts the if conditions for adding rockchip,cru to required.

Fixes: 510f1c133aed ("ASoC: dt-bindings: rockchip: add i2s-tdm bindings")
