Fix functionality on Giga CM4 core

[facchinm]

Requires arduino/ArduinoCore-mbed#741

Should fix #330 and many other issues.

The firmware cannot be uploaded yet so the mac address will be AA:AA:AA:AA:AA:AA

sorry, I'm not very familiar with GitHub... so has the problem been solved?

@Nocentinia we'll be happy to help you to learn how GitHub works if you ask that question over on Arduino Forum:

https://forum.arduino.cc/

Unlike the forum, where unstructured free ranging discussion is appropriate and welcome, we expect the discussions in Arduino's issue and pull request threads to be kept very tightly focused. Please only comment in these threads if you have something of value to add that is unique and directly relevant to the subject matter. The maintainers and developers of these projects should carefully monitor all comments for important information. That becomes very time consuming if there is a lot of "noise" (even if there is only a little noise in each repo, it adds up to a lot in aggregate across the hundreds of repositories we monitor), which hinders the ability for them to do the productive work that benefits the entire Arduino community.

Thanks in advance for your cooperation.

@facchinm is there an approximate ETA on this being merged since the ArduinoCore patch has been released?
