Remarkable port (#5828)
Touchscreen is mirrored in X & Y and has a different resolution from the eink panel.

Uses systemd for time/date/suspend/poweroff/reboot
Two systemd units for platform integration. button-listen is a very
simple launcher.
to-do: add support for wifi by implementing  a wpa supplicant dbus client.
