[PATCH v4 10/14] riscv: dts: canaan: use custom compatible for k210 i2s

From: Conor Dooley <conor.dooley at microchip.com>

The devicetrees using the Canaan k210 all have a sound-dai-cells value
of 1, whereas the standard binding example for the DesignWare i2s and
other use cases suggest 0. Use a k210 specific compatible which
supports this difference.
