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.
