[PATCH v3] ARM: dts: Gateworks GW5520 support (i.MX6)

[Tim Harvey <tharvey-UMMOYl/HMS+akBO8gow8eQ@public.gmane.org>]

Add support for the Gateworks GW5520 board.

Signed-off-by: Tim Harvey <tharvey-UMMOYl/HMS+akBO8gow8eQ@public.gmane.org>
---
Changes in v3:
 - remove gpiogrp and hog
 - fix state on pcie reset
 - remove unused input bindings include

Changes in v2:
 - use GPIO constants
 - move gpio pins from hoggrp to gpiogrp
 - use proper pad conf instead of 0x80000000
 - moved iomuxc to bottom for readability
 - pulled gpioledsgrp into iomuxc
 - fix whitespace errors
