Add device tree support and board enablement for audio on the
RZ/G3E SMARC EVK with a Dialog DA7212 codec.

This series includes:
  - CPG clock binding update for optional audio clock inputs
  - CPG driver support for RZ/G3E audio clocks and resets
  - Audio clock input nodes for RZ/V2H family DTSIs
  - R-Car Sound node for RZ/G3E SoC DTSI
  - Board-level enablement: I2C1, Versa3 clock generator, audio
    pinmux, and DA7212 codec on SMARC EVK

Audio configuration on SMARC EVK:
  - Codec: Dialog DA7212 on I2C1
  - Playback: SSI3
  - Capture: SSI4 -> SRC0 -> DVC0
  - MCLK: 12.288MHz from Versa3 clock generator
  - Format: I2S, R-Car Sound as clock master
  - SSI4 shares clock pins with SSI3 (shared-pin)

Changes:

v3:
 - Splitout from v2 [1]
 - No code changes

v2:
 - Fix Rob's comment on  maxItems not needed with items lists.
 - Drop DMA ACK second cell from DT specifier
