arm64: tegra: Add Host1x and VIC on Tegra264
Tegra264 has a host1x instance with a VIC (video image compositor). Other multimedia engines have moved outside host1x. Stream IDs are now namespaced by device rather than being defined globally -- however, the only engine we have using context isolation is VIC so we only define VIC's range of context devices.
