coresight: etm4x: fix wrong check of etm4x_sspcicrn_present()
According to Embedded Trace Macrocell Architecture Specification
ETMv4.0 to ETM4.6 [0], TRCSSPCICR<n> is present only if all of
the following are true:
- TRCIDR4.NUMSSCC > n.
- TRCIDR4.NUMPC > 0b0000.
- TRCSSCSR<n>.PC == 0b1.
Comment for etm4x_sspcicrn_present() is align with the specification.
However, the check should use drvdata->nr_pe_cmp to check TRCIDR4.NUMPC
not nr_pe.
