qcacmn: Restore WMI_DFS_RADAR_EVENTID for Rome FW

Currently WMI handler for WMI_PHYERR_EVENTID is used to handle DFS and
spectral scan phy errors; but Rome FW still uses WMI_PHYERR_EVENTID
and WMI_DFS_RADAR_EVENTID and does not have spectral scan phy errors.

Restore WMI_PHYERR_EVENTID and WMI_DFS_RADAR_EVENTID as Rome FW
requirement.
