dt-bindings: Add bindings for Tegra234 Host1x and VIC 



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.
