coresight-tpdm: Add nodes to configure pattern match output
Add nodes to configure trigger pattern and trigger pattern mask. Each DSB subunit TPDM has maximum of n(n<7) XPR registers to configure trigger pattern match output. Eight 32 bit registers providing DSB interface trigger output pattern match comparison. And each DSB subunit TPDM has maximum of m(m<7) XPMR registers to configure trigger pattern mask match output. Eight 32 bit registers providing DSB interface trigger output pattern match mask.
