[PATCH 05/10] ARM: tegra: Add Tegra114 DSI support

[Thierry Reding]

Add device tree nodes for the DSI controllers found on Tegra114 SoCs.

Signed-off-by: Thierry Reding <treding at nvidia.com>
---
Changes in v4:
- add reset and reset-names properties

Changes in v3:
- add #address-cells and #size-cells properties for DSI bus
- update for revised MIPI calibration bindings
- add low-power clocks

Changes in v2:
- use a comment to describe which pads need calibration
