[PATCH 2/4] ARM: dts: at91: sama5d2: mark secumod as a GPIO controller

[Eugen.Hristev]

From: Andrei Stefanescu <andrei.stefanescu@xxxxxxxxxxxxx>

The Security Module exposes the PIOBU pins which an be used
as regular GPIOs. The PIOBU pins are special because they do
not lose their voltage during suspend-to-mem.

This patch marks the secumod as a GPIO controller.
