libfdt: Add fdt_setprop_empty() Device trees can contain empty (zero length) properties, which are often used as boolean flags. These can already be created using fdt_setprop() passing a length of zero and a pointer which is ignored. It is safe to pass NULL, but that may not be obvious from the interface. To make it clearer, add an fdt_setprop_empty() helper macro. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
