ASoC: renesas: rz-ssi: Add suspend to RAM support
The SSIF-2 IP is available on the Renesas RZ/G3S SoC. The Renesas RZ/G3S
SoC supports a power-saving mode where power to most of the SoC
components is turned off. Add suspend/resume support to the SSIF-2 driver
to support this power-saving mode.
On SNDRV_PCM_TRIGGER_SUSPEND trigger the SSI is stopped (the stream
user pointer is left untouched to avoid breaking user space and the dma
buffer pointer is set to zero), on SNDRV_PCM_TRIGGER_RESUME software reset
is issued for the SSIF-2 IP and the clocks are re-configured.
