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 display. WiFi is untested (no dispaly or UART RX makes it hard to test), but should work with the current upstream driver. As it's untested it's not included in this commit.
