From: Mikko Perttunen <mperttunen@xxxxxxxxxx>
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.
Signed-off-by: Mikko Perttunen <mperttunen@xxxxxxxxxx>

v2:
* Add back 'required' for resets/reset-names on older SoCs
* Simplified reg descriptions
* Updated commit message
v3:
* Split out bracketing change in example
