ASoC: dt-bindings: renesas,rz-ssi: Update interrupts and interrupt-names properties

From R01UH0914EJ0120 Rev.1.20 HW manual, for full duplex channels
(SSI0/1/3) dma_rt interrupt has now being marked as reserved and similarly
for half duplex channel (SSI2) dma_rx and dma_tx interrupts have now being
marked as reserved (this applies to RZ/G2L and alike SoC's). This patch
updates the binding doc to match the same.

While at it also updated the example node.
