qcacmn: Enable additional two HTT data services

Enable HTT_DATA2_MSG_SVC and HTT_DATA3_MSG_SVC, using only
rx legs, CE 9 and 10, respectively. Add required CE entries
to the map that gets sent to the FW, and define the latter
service.
Rename htc_endpoint to htc_tx_endpoint in htt_pdev to
represent the role better.
