[U-Boot] [PATCH v3] ARM: tegra: Add Tegra20 SPI device nodes

[Mirza Krak]

From: Mirza Krak <mirza.krak at hostmobility.com>

Add the device tree node for the SPI controllers found on Tegra20 SOCs.

Signed-off-by: Mirza Krak <mirza.krak at hostmobility.com>

Changes in v2:
* Dropped tegra30-slink compatible string, based on comment from Thierry Reding on v1 patch

Changes in v3:
* Copy/paste spi device nodes from Linux (4.1.6)

Did an attempt of copying tegra20.dtsi from Linux but it broke USB and LCD from what I could see on my Colibri T20, and I dropped that as it was out of scope of my patch.
