[PATCH v6 09/17] rtc: rzn1: Use pm_runtime_put_sync()

From: Lad Prabhakar <[email protected]>

pm_runtime_put() may trigger the idle check after pm_runtime_disable()
is run as part of devm_pm_runtime_enable()'s cleanup action, leaving
runtime PM active.

Use pm_runtime_put_sync() to ensure the idle check runs synchronously.
