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.
