Subject: [PATCH 3/4] misc: rtsx: Cleanup power management ops
- Use cancel_delayed_work_sync to ensure there's no race with
carddet_work.
- Remove device_wakeup_disable to save some CPU cycles. If the device
really has ACPI _DSW then the wakeup should be disabled in probe
routine.
- Remove fetch_vendor_settings from runtime resume routine, since they
are already saved in "struct rtsx_pcr".
