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.
