Pull clk api update from Stephen Boyd:
 "Small patch to add the clk_bulk_prepare_enable() and
  clk_bulk_disable_unprepare() API to the newly introduced
  clk bulk APIs.

  It would be good to get this into the -rc1 so that other
  driver trees can use it for code targeted for the next
  merge window"
