[platforms: PATCH 02/12] Marvell/Library: ArmadaBoardDescLib: Add GPIO information

[Marcin Wojtas <mw@semihalf.com>]

This patch extends library with GPIO devices per-board
description. Both embedded SoC controllers and
I2C IO expanders are supported. Add a helper routine
for obtaining information about the latter.
