Currently this package only depends on PCI support, this also adds a 
dependency to USB.

I think the beast approach is to split this into a core part with the 
rtw88_core.ko and the rtw88_88*.ko files, one package with rtw88_pci.ko 
and one with rtw88_usb.ko. Then you can install it on a system with only 
USB and on a system with only PCIe support.
