fdt: Add option to default to most compatible conf in a fit image
When booting a fit image with multiple configurations, the user either has to specify which configuration to use explicitly, or there has to be a default defined which is chosen automatically. This change adds an option to change that behavior so that a configuration can be selected explicitly, or the configuration which has the device tree that claims to be compatible with the earliest item in U-Boot's device tree. In other words, if U-Boot claimed to be compatible with A, B, and then C, and the configurations claimed to be compatible with A, D and B, D and D, E, the first configuration, A, D, would be chosen. Both the first and second configurations match, but the first one matches a more specific entry in U-Boot's device tree. The order in the kernel's device tree is ignored.
