I didn't like these #ifdefs either, but davinci doesn't have runtime PM, and I don't think blackfin does either. But, rather than the ifdef here, this could be done with different pointers in struct dev_pm_ops based on the arch. Also, this shouldn't be based on CONFIG_PM_RUNTIME, but rather on the arch. We can still enable runtime PM on davinci for other subsystems (PCI, USB core, etc.) but not have it supported for on-chip devices.
