ARM: dts: exynos: Add support for Samsung Klimt WiFi
Klimt WiFi has the product name Samsung Galaxy Tab S 8.4". Board is
based on Exynos 5420, and has similar hardware to Chagall WiFi, but
with a smaller battery, smaller screen and another touchscreen
controller.
The device tree added here contains support for:
- UART access through a micro-usb cable with 619 kOhm between ID & GND
- Accessing the internal eMMC storage
- Accessing an external SD card
- USB, after configuration it is possible to ssh into the device
through a usb cable
