Determining which kernel config options need to be enabled for a
given devicetree can be a painful process. Create a new tool to
find the drivers that may match a devicetree node compatible,
find the kernel config options that enable the driver, and
optionally report whether the kernel config option is enabled.

If kernel config options are not properly set, "make scripts" will not
compile dtc. Update the unable to find dtc error message to check
the kernel config and give better advice on how to create dtc.
Reword another error message to increase clarity.

Create script to diff device trees.
The device tree can be in any of the forms recognized by the dtc compiler:
- source
- binary blob
- file system tree (from /proc/devicetree)
If the device tree is a source file, then it is pre-processed in the
same way as it would be when built in the linux kernel source tree
before diffing.
