Add the mesh configuration parameters dot11MeshHWMProotInterval and
dot11MeshHWMPactivePathToRootTimeout to be used by proactive PREQ mechanism.
Signed-off-by: Chun-Yeow Yeoh <yeohchunyeow@xxxxxxxxx>

v2: avoid renumbering the old command ids (Johannes)
v3: adhere the coding style and add kernel-doc (Johannes)
v4: rebase to coding-style/kernel-doc patch (Johannes)
