Some of the QCA BTSoC ROME functions, are used for different versions or different make of BTSoC's. Instead of duplicating the same functions for new chip, update names of the functions that are used for both chips to keep this generic and would help in future when we would have new BT SoC. To have generic text in logs updated from ROME to QCA where ever possible. This avoids confusion to user, when using the future Qualcomm Bluetooth SoC's. Updated BT_DBG, BT_ERR and BT_INFO with bt_dev_dbg, bt_dev_err and bt_dev_info where ever applicable.
