libfdt: Implement fdt_get_property_namelen() and fdt_getprop_namelen()
As well as fdt_subnode_offset(), libfdt includes an fdt_subnode_offset_namelen() function that takes the subnode name to look up not as a NUL-terminated string, but as a string with an explicit length. This can be useful when the caller has the name as part of a longer string, such as a full path. However, we don't have corresponding 'namelen' versions for fdt_get_property() and fdt_getprop(). There are less obvious use cases for these variants on property names, but there are circumstances where they can be useful e.g. looking up property names which need to be parsed from a longer string buffer such as user input or a configuration file, or looking up an alias in a path with IEEE1275 style aliases. So, since it's very easy to implement such variants, this patch does so. The original NUL-terminated variants are, of course, implemented in terms of the namelen versions.
