ARM: dts: renesas: Genmai: Update audio codec device node

Meanwhile, bindings for the audio codec exist.  Add #sound-dai-cells
property and limit max frequency accordingly.

  codec@0: '#sound-dai-cells' is a required property
  codec@0: spi-max-frequency: 5000000 is greater than the maximum of 526000
