Issue description

The manual solution for Ubuntu here should be adapted and automated such that it runs out of the box:

# dmesg
[  947.674489] Bluetooth: hci0: BCM: chip id 102
[  947.690495] Bluetooth: hci0: BCM20703A1
[  947.691487] Bluetooth: hci0: BCM (001.001.005) build 0000
[  947.691533] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6410.hcd failed with error -2
[  947.691534] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6410.hcd not found

You could adapt this project or this package and create a new package in: pkgs/os-specific/linux/firmware
If the license is set to unfree, hydra won't build it automatically. That way license conditions would not be hurt. The resulting packages can be added to:

hardware = {
  firmware = [pkgs.<packagename>];
  enableAllFirmware = true;

It might also an option to add the package to ./nixos/modules/hardware/all-firmware.nix. Then everybody using enableAllFirmware would automatically get it.
