Sometimes it is useful to iterate through all devices in a uclass and skip over those which do not work correctly (e.g fail to probe). Add two new functions to provide this feature.
The caller must check the return value each time to make sure that the device is valid. But the device pointer is always returned.

Changes in v2:
- Return even device, even those with errors
- Rename the functions

This patch has been sitting around for a while. Does anyone think it is useful?
