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

[Nicolas Frattaroli <frattaroli.nicolas@xxxxxxxxx>]

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.
