Subject: [PATCH v9 1/2] ASoC: rt5514: Add devicetree bindings for rt5514-spi

Add devicetree bindings documentation file for rt5514 spi dsp codec.

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

+- compatible : "realtek,rt5514" or "realtek,rt5514", "realtek,rt5514-spi".

+- reg : The SPI address of the device.

+Optional properties:

+- interrupt-parent: Should be the phandle for the interrupt controller
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
