There is no need to keep a reference to the PLD struct around,
it is only used once the get the sensor orientation.
Rename cio2_bridge_parse_orientation() to cio2_bridge_get_orientation()
and make it also get + put the PLD.
This is a preparation patch for making the cio2-bridge code more generic
so that it can be shared with the atomisp driver.
