Again about HOME_INDEX in step/dir mode

Step/Dir index support with Mesa hardware does not need any
programming, just the correct firmware and a minor hal change:
 
Replacing the encoder index  enable with the stepgen index enable.

It's likely possible to do this with programming but that has the disadvantage
of having an index detection uncertainly of a thread period.

Does your current setup have inputs available for index inputs?

I will try to implement this using the GPT chat

A quick note to make it easier to find:
Instead of
“hm2_board.0.encoder.1.index-enable”
Use
“hm2_board.0.stepgen.1.index-enable”
