Delta TN48M switches have a Lattice CPLD that serves multiple purposes
including being a GPIO expander and providing various resets.

This patch series focuses on providing support for the CPLD provided
peripherals that are needed for the switch to function.

The series has been refined over the last 9 months or so and currently
all of the code has been reviewed and is ready for merge.
We are still hovewer waiting for the DT bindings to be reviewed for a
while, but hopefully Rob will provide feedback soon.

Changes in v10:
* Rebase onto 5.17-rc1
