ARM: dts: Introduce HPE GXP Device tree

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.
