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@rock-chips.com> ---
Changes in v10: Put rt5514-i2c doc & rt5514-spi doc together.
Changes in v9: Address comments from Brian.
