[PATCH] arm: mvebu: Add SPI flash on Armada XP-GP board

This patch adds an SPI master device node for Armada XP-GP board.
This master node is an SPI flash controller 'n25q128a13'.

Since there is no 'partitions' node declared, one full sized
partition named as the device will be created.

This patch depends on:

 1. Gregory's patch for Armada XP GP board:
      arm: mvebu: support for the new Armada XP development board(DB-MV784MP-GP)

 2. My previous patch for SPI on Armada 370/XP:
      arm: mvebu: Add support for SPI controller in Armada 370/XP

And don't forget to compile the SPI flash driver, CONFIG_MTD_M25P80=y
