OMAPDSS: fix warnings if CONFIG_PM_RUNTIME=n
If runtime PM is not enabled in the kernel config, pm_runtime_get_sync() will always return 1 and pm_runtime_put_sync() will always return -ENOSYS. pm_runtime_get_sync() returning 1 presents no problem to the driver, but -ENOSYS from pm_runtime_put_sync() causes the driver to print a warning. One option would be to ignore errors returned by pm_runtime_put_sync() totally, as they only say that the call was unable to put the hardware into suspend mode. However, I chose to ignore the returned -ENOSYS explicitly, and print a warning for other errors, as I think we should get notified if the HW failed to go to suspend properly.
