Support for this property has been introduced in 2010 with commit
9d5da3a9b849 ("mtd: extend physmap_of to let the device tree specify the
parition probe") but it was never documented. Fix this by adding a
proper description and example.

+- linux,part-probe: if present, this property should contain a list of strings
+  with partition probes to be used for the flash device. A role of partition
+  probe (parser) is to read/construct partition table and register found
+  partitions. Getting partition table may be platform or device specific so
+  various devices may use various Linux drivers for this purpose.
+
 Example:
 
 	flash@0 {
 		label = "System-firmware";
+		linux,part-probe = "cmdlinepart", "ofpart";
 
 		/* flash type specific properties */
 	};
