Since the new keypad module is taking over gamepad functionality,
I'm switching to it. If this works well, I will make the change
for the remaining boards.
The newest version for the Stage library for PewPewM4 no longer contains
embedded graphics, which frees enough space in flash to enabled back
AnalogIO and also add USB_HID. There is still ~192 bytes left free.
If new additions to CircuitPython make it grow further, we can disable
USB_HID again.
We're moving towards a co-processor model and a Wiznet library is
already available.
New native APIs will replace these for chips with networking like the
ESP32S2 but they won't be these.
Since Actions passed on the previous commit, where this computed value
was checked against the specified value (if any), this is no net change,
except that we no longer need to specify it for particular boards or
ports.
