powerpc/windfarm: const'ify and add "priv" field to controls & sensors
const'ify the sensor ops and name and add a void* for use by the control and sensor drivers to point back to their private data, avoiding the need to create a wrapper data structure per sensor or control instance. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
