coresight-tpdm: Add support to enable the lane for MCMB TPDM
Add the sysfs file to set/get the enablement of the lane. For MCMB
configurations, the field "E_LN" in CMB_CR register is the
individual lane enables. MCMB lane N is enabled for trace
generation when M_CMB_CR.E=1 and M_CMB_CR.E_LN[N]=1. For lanes
that are not implemented on a given MCMB configuration, the
corresponding bits of this field read as 0 and ignore writes.
