[U-Boot] [PATCH v2 7/9] dm: at91: Convert snapper9260 to use driver model

[Simon Glass]

Convert this at91sam9260-based board to use driver model. This should serve
as an example for other similar boards. Serial and GPIO are supported so
far.

Changes in v2:
- Update platform data and header #include for the new driver name
