Subject: [PATCH net-next 3/3] net: ipa: extend the INDICATION_REGISTER request

The specified format of the INDICATION_REGISTER QMI request message
has been extended to support two more optional fields:
  endpoint_desc_ind:
    sender wishes to receive endpoint descriptor information via
    an IPA ENDP_DESC indication QMI message
  bw_change_ind:
    sender wishes to receive bandwidth change information via
    an IPA BW_CHANGE indication QMI message

Add definitions that permit these fields to be formatted and parsed
by the QMI library code.
