ESP32-H2 missing GPIO pins above 20

[bitmagier]

The lib exposes GPIO Pins 0..20 for the ESP32-H2 GPIO.
As one can see in section "2.1 Pin Layout" in the Datasheet, there are also the following hardware pins available to use:
Pins: 22, 25, 26, 27

Especially pin 22 and pin 25 are extremely useful, because they are also exposed in the ESP32-H2-WROOM-03 model (which is also used by me).

I suggest to simply add these GPIO pin numbers in esp-idf-hal.

I don't have a h2 around, so what would be most efficient - if you don't mind - is if you could actually open a PR adding those. This way you could also test if these pins do actually work.

[bitmagier]

.. I'm just preparing one.

#501

Unfortunately the main build seems to be broken at the moment. I get the same compile-errors locally as the pipeline shows on github.

Use a slightly older nightly or the ESP toolchain. What is broken is upstream STD in nightly since ~ 2 days.

Thanks, my local build works.
Validating pin functionality on hardware-level is the next best thing to to.
Will need some time.

A added also pins 23+24 (used by Serial debug interface)

I successfully verified hardware functionality for pins 22 and 25.
The other 4 added pins should work too. Since they are not directly recommended to be used, one may play around with them by himself.

PR #501 is updated, works for me and is ready to be pulled.
