Subject: [PATCH v10] ASoC: rt5514: Add devicetree binding support for rt5514-spi

Add devicetree binding support for rt5514 spi dsp codec.

Also update rt5514 i2c dt-binding's compatible to distinguish it from
rt5514 spi.

Signed-off-by: Jeffy Chen <jeffy.chen@...k-chips.com>

Changes in v10:
Put rt5514-i2c doc & rt5514-spi doc together.

Changes in v9:
Address comments from Brian.
