Revert "sh-sci / PM: Avoid deadlocking runtime PM"
This reverts commit 048be431e4 (sh-sci / PM: Avoid deadlocking runtime PM, from Rafael J. Wysocki <rjw@sisk.pl>, 2012-03-09). In order to get console PM work properly, we should implement uart_ops ->pm() operation, rather than sprinkle band-ading runtime PM calls in the driver.
