Marek Szyprowski 9f7d27fa1b ARM: dts: exynos: enable MFC device for all boards
MFC device can be used without any external hardware dependencies (when
IOMMU is enabled), so it can be enabled by default (like it has been
already done for Exynos 542x platforms). This unifies handling of this
device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still
include exynos-mfc-reserved-memory.dtsi to enable using this device
without IOMMU being enabled.
