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.
