'/aliases' node property names haven't ever been documented. There's some names such as 'serial' which are pretty much standard. Then there are other (mostly) platform specific names which sneak in as a way to have indices for devices. Let's add a schema so that any new alias names can be reviewed. The list of property names consists of common aliases which are widely used and ones which are used by the kernel, but are marked deprecated. New users of deprecated names are allowed, but discouraged. There's still more names which are present in DT files, but not used in the kernel or u-boot (it's not trivial to check u-boot usage though). These will generate warnings.
