ARM: dts: tegra20: Update Memory Controller node to the new binding

digetx · joergroedel · commit 334175243cc6 · 2019-01-16T13:54:11.000+01:00
Device tree binding of Memory Controller has been changed: GART has been
squashed into the MC, there are a new mandatory clock and #iommu-cells
properties, the compatible has been changed to 'tegra20-mc-gart'.
