In some rare cases it is useful to be able to locate a device given a device tree node offset. An example is when you have an alias that points to a node and you want to find the associated device. The device may be SPI, MMC or something else, but you don't need to know the uclass to find it.
Add a function to do a global search for a device, given its device tree offset.
