media: i2c: maxim-serdes: add MAX96717 driver

Add a new MAX96717 driver that also supports MAX9295A, MAX96717F and
MAX96793.

Integrate it with the common serializer framework, while keeping
compatibility with existing usecases, avoiding code duplication, and
also enabling more features across all chips.
