Bug: Channel list harcoded for US. Missing channels for Europe

[OhSoGood]

Hi, Thank you for your super work on 88x2bu. Linux's built-in rtw88_8822bu driver was not working for me.

Yet, I faced a small but annoying issue: your channel list are hardcoded in rtw_rf.c and match the US and not Europe. For instance, in Europe, we also have channels 32, 68 and 96.

Is that something you could integrate in your driver? At least a simple mechanism (hack?), maybe not the full country-regulation. That would be greatly appreciated!
