[PATCH v2] PM: runtime: replace pm_runtime_resume_and_get with pm_runtime_resume_and_get_sync

[Zhang Qilong <zhangqilong3@huawei.com>]

In the pm_runtime_resume_and_get, pm_runtime_resume() is
synchronous. Caller had to look into the implementation
to verify that a change for pm_runtime_resume_and_get [0].
So we use pm_rauntime_resume_and_get_sync to replace it to
avoid making the same mistake while fixing
pm_runtime_get_sync.
