i2c: Fix checks which cause legacy suspend to never get called
For devices which are not adapted to runtime PM a call to
pm_runtime_suspended always returns true.
Hence the pm_runtime_suspended checks below prevent legacy
suspend from getting called.
So do a pm_runtime_suspended check only for devices with a
dev_pm_ops populated (which hence do not rely on the legacy
suspend.)
