Subject: [PATCH 15/22] ARM: dts: add a devicetree for Teltonika RUT1xx

This devicetree is simply based on the board file in
arch/arm/mach-gemini/board-rut1xx.c and contain the
equivalent platform data, mainly just moving the GPIOs
from the global numberspace to explicitly reference their
parent GPIO.
