ARM: shmobile: rcar-gen2: Remove unused rcar_gen2_read_mode_pins() 

After
  1. commit 9f5ce39ddb ("ARM: shmobile: rcar-gen2: Obtain extal
     frequency from DT"),
  2. commit 80951f04c3 ("ARM: shmobile: rcar-gen2: Stop passing
     mode pins state to clock driver"),
  3. and handling of debug resource reset,
there are no more users of rcar_gen2_read_mode_pins() left.
Remove the function and its support definitions.
