Initial driver and binding document changes for supporting flash LED
module in Qualcomm Technologies, Inc. PMICs.

Changes in V8:
  1. Introduce a helper function 'flcdev_to_qcom_fled()'.
  2. Rename 'struct qcom_flash_chip' as 'struct qcom_flash_data' and
     remove 'qcom_flash_led' data pointers from it to avoid interwoven
     reference. Also remove the 'dev' pointer.
  3. Remove 'v4l2_flash' data pointer in 'struct qcom_flash_led' and
     move it to 'struct qcom_flash_data'.
