coresight-tpdm: Add pattern registers support for CMB

Timestamps are requested if the monitor’s CMB data set unit input
data matches the value in the Monitor CMB timestamp pattern and mask
registers (M_CMB_TPR and M_CMB_TPMR) when CMB timestamp enabled
via the timestamp insertion enable register bit(CMB_TIER.PATT_TSENAB).
The pattern match trigger output is achieved via setting values into
the CMB trigger pattern and mask registers (CMB_XPR and CMB_XPMR).
After configuring a pattern through these registers, the TPDM subunit
will assert an output trigger every time it receives new input data
that matches the configured pattern value. Values in a given bit
number of the mask register correspond to the same bit number in
the corresponding pattern register.
