ASoC: renesas: rz-ssi: Rely on the ASoC subsystem to runtime resume/suspend the SSI

The ASoC subsystem takes care of runtime resume/suspend the audio
devices when needed. Just enable the runtime PM on the SSI driver and
let the subsystem runtime resume/suspend it. While at it use directly
the devm_pm_runtime_enable().
