On board keys on Origen board can serve as wakeup sources,
hence they are marked accordingly in the device tree file.

Currently all boards must explicitly disable all unused device tree
nodes of unused components (e.g. i2c, sdhci, etc...). This makes it
necessary to all boards to be aware of all components on the SoC, which
in turns makes board dts files longer and more difficult to maintain
(e.g. adding new components to SoC-level tree requires adding nodes with
status="disabled" to every board).

This patch changes "status" of all optional components in SoC-level dts
file to "disabled", adds status="okay" to respective nodes of used
components in dts of all boards and removes all nodes with only
status="disabled" from boards dts.

Commit f447ed8b ("gpio: samsung: add flags specifier to
device-tree binding") adds a flag to represent active low state
for gpio line. Since gpio-keys on Origen board are active low,
using this flag to represent the same.

Add device nodes for the three instances of spi controllers in
EXYNOS4 platforms. Enable instance SPI 2 for SMDKV310 board and
disable all spi instances for Origen board.

Add initial dts file for EXYNOS4210 SoC. This dts file describes
the SoC specific devices and properties. Along with this, add dts
file for Samsung's SMDKV310 board and Insignal's ORIGEN board which
uses the EXYNOS4210 dts file and extends it to describe the board
specific properties.
