ice: add support for DSCP QoS for IDC
The ice driver provides QoS information to auxiliary drivers
through the exported function ice_get_qos_params. This function
doesn't currently support L3 DSCP QoS.
Add the necessary defines, structure elements and code to support
DSCP QoS through the IIDC functions.
