[PATCH] dt-bindings: soc: Add HPE GXP SOC binding

[nick . hawkins]

From: Nick Hawkins <nick.hawkins@xxxxxxx>

Description: This binding will be used in creating the HPE GXP
 architecture. GXP is the name of the HPE SoC.
This SoC is used to implement BMC features of HPE servers
(all ProLiant, Synergy, and many Apollo, and Superdome machines)
It does support many features including:
        ARMv7 architecture, and it is based on a Cortex A9 core
        Use an AXI bus to which
                a memory controller is attached, as well as
                 multiple SPI interfaces to connect boot flash,
                 and ROM flash, a 10/100/1000 Mac engine which
                 supports SGMII (2 ports) and RMII
                Multiple I2C engines to drive connectivity with a
				 host infrastructure
                A video engine which support VGA and DP, as well as
                 an hardware video encoder
                Multiple PCIe ports
                A PECI interface, and LPC eSPI
                Multiple UART for debug purpose, and Virtual UART for
                 host connectivity
                A GPIO engine.
