[PATCH v2 33/33] dtoc: Generate device instances

[Simon Glass]

Add support for generating a file containing udevice instances. This
avoids the need to create these at run time.

Update a test uclass to include a 'per_device_plat_auto' member, to
increase test coverage.

Add another tab to the driver_info output so it lines up nicely like the
device-instance output.

Changes in v2:
- Drop patches previously applied
- Update cover letter
- Fix the naming for uclass_plat_name so it is different from uclass_priv
- Tidy up tabbing to make the code output line up better
- Add a summary to the top of the generated file
