Subject: [PATCH v2 15/25] ASoC: sh: rz-ssi: Rely on the ASoC subsystem to runtime resume/suspend the SSI

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

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().
