Subject: [PATCH v5 17/20] media: hantro: Stop using H.264 parameter pic_num

The hardware expects FrameNumWrap or long_term_frame_idx. Picture
numbers are per field, and are mostly used during the memory
management process, which is done in userland. This fixes two
ITU conformance tests:

  - MR6_BT_B
  - MR8_BT_B
