[POWERPC] Update MTD OF documentation

This updates the Documentation/powerpc part of the MTD OF
implementation with the new field probe-type. Its support has already
been implemented in MTD part (drivers/mtd/maps/physmap_of.c).

-       for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
      - partitions : Several pairs of 32-bit values where the first value is
        partition's offset from the start of the device and the second one is
        partition size in bytes with LSB used to signify a read only
