Tegra20/Tegra30 DSI is quite similar to Tegra114+ apart MIPI calibration
logic and clocks. With a few minor tweaks, existing tegra DSI driver
should work on Tegra20/Tegra30 devices just fine. Tested on
Motorola Atrix 4G (T20) and ASUS VivoTab RT TF600T (T30).
This patchset depends on Tegra20/Tegra30 CSI bringup since both share
MIPI calibration logic. Ideally these patches should be picked after
CSI bringup but they will not break anything even if picked before
CSI patches.

Changes in v2:
- removed all MIPI calibration, it is handled within CSI bringup
- added per-soc structures into of_match
- added fix for hang caused by register access with uninited hw
