Raspberry Pi 4 Module

Do not import this module into the main default.nix file. Otherwise the other systems aren't buildable anymore because some options from the nixos-hardware input get applied immediately.

Just import it in any system you need with the following code where variant is either ethernet or usb. ethernet is for a Pi which is intended as a server and is connected with a fixed IP to the network. usb is for a Raspberry Pi which can be connected via USB-C to another device, e.g. an iPad. The ethernet port is configured to get its IP via DHCP and via uSB-C the Pi is reachable via the IP provided in the configuration.
