[PATCH 27/31] arm64: dts: renesas: r9a08g045: Add SSI nodes

[Claudiu <claudiu.beznea@xxxxxxxxx>]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

Add DT nodes for the SSI IPs available on the Renesas RZ/G3S SoC. Along
with it external audio clocks were added. Board device tree could use it
and update the frequencies.
