In device trees in the world, properties consisting of a single 64-bit integer are not as common as those consisting of a single 32-bit, cell sized integer, but they're common enough that they're worth including convenience functions for. This patch adds helper wrappers of fdt_setprop_inplace(), fdt_setprop() and fdt_appendprop() for handling 64-bit integer quantities in properties. For better consistency with the names of these new *_u64() functions we also add *_u32() functions as alternative names for the existing *_cell() functions handling 32-bit integers.
