NixOS profiles covering hardware quirks.

** Setup

Add and update ~nixos-hardware~ channel:

  : $ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
  : $ sudo nix-channel --update nixos-hardware

Then import an appropriate profile path from the table below. For example, to
enable ThinkPad X220 profile, your ~imports~ in ~/etc/nixos/configuration.nix~
should look like:

  : imports = [ <nixos-hardware/lenovo/thinkpad/x220> ./hardware-configuration.nix ];
