[PATCHv2 7/8] ARM: mvebu: add suspend/resume DT information for Armada 388 GP

[Thomas Petazzoni]

This commit improves the Armada 388 GP Device Tree description to
describe the 3 GPIOs that are used to connect the SoC to the PIC
micro-controller that we talk to shutdown the SoC when entering
suspend to RAM.
