I have now moved the RESET/FEED_HOLD/CYCLE_START pin definitions to aux inputs and claim them from there if enabled.

FYI new in the latest commit is that two additional probe inputs are supported. These can be claimed explicitly by assigning to a given pin or from unclaimed pins.

This define has been removed and associated code has been permanently enabled. Enumeration failed completely if not commented out?

Only add the new stuff and leave it commented out...

I put the FlexGPIO in its own plugin repo instead of in the driver code (like the other I2C expanders) as it is fairly generic and could be used on other boards pretty easily.
I did find I had to extend some of the arrays in the xbar to support the additional aux io ports. And I hope I used the new API correctly to assign and enumerate the ports.
