Note that this doesn't say anything about (in)compatibility with generic
R-Car Gen3 compatible devices (hint: yaml conversion?).

New features:
- Slave Clock Stretch Select,
- Fast Mode+ Enable,
- Enhanced First Bit Setup Cycle configuration.

Looks like the R-Car V3U variant can be treated as a generic R-Car Gen3
variant (lacking the new features, of course).
