As part of the runtime PM support, bus-level code can automatically
handle the enable/idle for each omap_device. There are, however, some
special cases where we don't want the bus-level layer to handle this,
and instead handle it manually.
Specific use cases are for omap_devices that are controlled
inside the idle path (like UART.)
