coresight-tpdm: Add nodes for dsb msr support
Add the nodes for DSB subunit MSR(mux select register) support. The TPDM MSR (mux select register) interface is an optional interface and associated bank of registers per TPDM subunit. The intent of mux select registers is to control muxing structures driving the TPDM’s’ various subunit interfaces.
