This commit is based on the DTS provide by reMarkable but ported to the latest kernel (instead of 4.14). I have removed references to non-upstream devices and have changed the UART so that the console can be accessed without having to open up the device via the OTG pogo pins. Currently the kernel boots, but there is no support for the dispaly, WiFi or the power controller chips.
