arm64: dts: renesas: r8a774a1: Add SSIU support for sound

Add SSIU support to the SoC DT as the sound driver supports
it now, and also since the sound driver can now handle
BUSIF0-7 via SSIU remove the no longer needed "rxu" and "txu"

Based on similar work from Kuninori Morimoto and Simon Horman in commits
8d14bfa074db ("arm64: dts: renesas: r8a7796: add SSIU support for
sound") and 10bd03fa896e ("arm64: dts: renesas: r8a7796: remove BUSIF0
settings from rcar_sound,ssi").
