Add support in the PCA9552 model for the PCA9535 and leverage it in
the catalina system model, which has a PCA9535 rather than a PCA9552.
We presently have two PCA95xx chips modelled:
- PCA9552: A 16-bit LED + GPIO controller.
- PCA9554: An 8-bit GPIO controller.
PCA9535 is a 16-bit GPIO controller. I considered creating a new model,
extending PCA9552, or extending PCA9554. The least code change seemed
to be extending PCA9552 but I could take another approach if desired.
