Add a devicetree description for the Librem 5 phone. The early batches
that have been sold are supported as well as the mass-produced device
available later this year, see https://puri.sm/products/librem-5/

This boots to a working console with working WWAN modem, wifi usdhc,
IMU sensor device, proximity sensor, haptic motor, gpio keys, GNSS and LEDs.

Is the compatible documented?

I'm not sure these two properties are coded correctly, you may want to
double check the bindings doc.

Nit: can we consistently put 'enable-active-high' after 'gpio' node?
