OMAP: PM: omap_device: add API to disable idle on suspend
By default, omap_devices will be automatically idled on suspend (and re-enabled on resume.) Using this new API, device init code can disable this feature if desired. NOTE: any driver/device that has been runtime PM converted should not be using this API. Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
