ARM: OMAP: omap_device: keep track of driver bound status
Use the bus notifier to keep track of driver bound status by adding a
new internal field to struct omap_device: _driver_status.
This will be useful for follow-up patches which need to know whether
or not a driver is bound in order to make intelligent omap_device
enable/idle decisions.
