[RFC 05/10] ARM: tegra: Add memory controller on Tegra124

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Add the memory controller and wire up the interrupt that is used to
report errors. Also add an #iommu-cells property to make the device
as an IOMMU.

Signed-off-by: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
