Two new files in raspberry-pi/common/: config-txt.nix lets you declare config.txt contents through hardware.raspberry-pi.configtxt.settings (RFC 42 style — plain values, null to remove, no enable/value wrappers). config-txt-defaults.nix has the same defaults as Raspberry Pi OS: vc4-kms-v3d, audio on, arm_boost, CM4 otg_mode, CM5 dwc2, etc. All mkDefault so they are easy to override. Not wired into board profiles yet — that comes with the RPi 5 sub-module work. Based on nvmd/nixos-raspberrypi.
