Nick Hawkins 2b7a89bc94 ARM: dts: Add device tree files for hpe gxp soc
The HPE SoC is new to linux. A basic device tree layout with minimum
required for linux to boot including a timer and watchdog support has
been created.

The dts file is empty at this point but will be updated in subsequent
updates as board specific features are enabled.
