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

Signed-off-by: Mirza Krak mirza.krak@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.
