ARM: DT: tegra: Add Tegra30 Beaver board support

Use engineering name 'Tegra20' instead of 'Tegra2'

This patch adds support for Tegra30 Beaver board in upstream kernel.

This patch adds support for Tegra30 Beaver board in upstream kernel.

Beaver board is a Tegra30 SoC based development board, it has following features:
- T30 or T33 SoC (Qual core ARM Cortex A9)
- 2 GB DDR3L
- 16 GB EMMC
- 1 SD slot
- 1 USB Standart A port and 1 USB micro AB port
- PCI-E Gig Ethernet
- Audio input/output
- SATA port
- HDMI output
- UART and JTAG

nvidia,beaver needs to be documented.

Hmmm. I guess we've managed not to document /any/ of the Tegra board-level compatible values. Bryan, could you make a separate patch to add all the existing board compatible values to Documentation/devicetree/bindings/arm/tegra.txt. The Beaver addition to that file can still be part of the Beaver-specific patch though.

Does it need to be documented? Then the "support a new platform only through DTS update" is no longer true. :)

In the past, I don't think we've strictly documented all derivative platform compatible values, just some of the reference ones?

Actually in every Tegra board dts file, there is a model string to describe this machine as well as a compatible board string, just like the "nvidia,beaver". So do we still need put this duplicated information in a document file? Or if this is the requirement of DeviceTree. I will do that. I think we have 12 boards need to add such document currently.
