[PATCH v8 2/7] watchdog: rzv2h: Use pm_runtime_put_sync()

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

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.
