mlxsw: reg: Add QoS Switch Traffic Class Table is Multicast-Aware Register 



This register configures if the Switch Priority to Traffic Class mapping
is based on Multicast packet indication. If so, then multicast packets
will get a Traffic Class that is plus (cap_max_tclass_data/2) the value
configured by QTCT.
