Support for ArmSoM Sige7

[JustusFriehl]

It would be cool to have support for the ArmSoM Sige7 because it is one of the cheaper entry points for the RK3588.
I hope that someone can make this happen i dont have one yet but i will try to help as soon as i have one.
Thank you in advance

I second this request. I do have one that I can test with, but I'll need to be guided through the process.
