device-pine64-pinephone: subpkgs for sway and x11 keyboard configs
related: https://gitlab.com/postmarketOS/pmaports/-/merge_requests/3843#note_1265868288
There's a pinephonen specific file in sxmo-utils upstream and apparently it shouldn't be there. It makes more sense to put it in device packages. (Ideally this should be added for the pinephone pro too)
