i2c: i801: Don't restore config registers on runtime PM
Restoring configuration registers is only needed when we hand control to the firmware. This is never the case with runtime power management. The device will autosuspend whenever not used, so avoid useless register writes by defining suspend/resume only, and not runtime_suspend/runtime_resume.
