driver: Add functions to free devices
struct device_d has some dynamically allocated members, namely .name and
.unique_name. These are normally not freed when a device is freed. Add
two functions to free these resources. free_device_res() only frees the
allocated members, but not the device itself. This is suitable for cases
where the device is embedded in another struct. free_device() frees the
allocated members along with the device itself. This can be called when
the device itself has been directly allocated.
Some users which should use these functions are also fixed in this
patch.
