qcacld-3.0: Convert SME code legacy channel ID usage

1) Change hdd_parse_plm_cmd's code to populate frequency
   list instead of channel ID list into struct
   plm_req_params.

2) Use frequencies instead of channel IDs in the following
   APIs' parameter/code:

   sme_set_plm_request
   csr_is_supported_channel

3) Stop populating channel freq list in function
   wma_plm_start, as the frequency list will be included
   in struct plm_req_params automatically.
