Tegra194 and later chips have a coherency fabric, so some devices can be
marked as DMA coherent to avoid unnecessary cache maintenance.

Update VIC and Host1x bindings for changes in Tegra234.
Namely,
- New compatible strings
- Sharded syncpoint interrupts
- Optional reset.
Also, fix the order of descriptions for VM/hypervisor
register apertures -- while the reg-names specification
was correct, the descriptions for these were switched.

Convert the Tegra host1x controller bindings from the free-form text
format to json-schema.
This also adds the missing display-hub DT bindings that were not
previously documented.
