dt-bindings: arm: qcom,coresight-tpdm: Add support for CMB element size

Browse Source 
Add property "qcom,cmb-elem-bits" to support CMB(Continuous
Multi-Bit) element for TPDM. The associated aggregator will read
this size before it is enabled. CMB element size currently only
supports 8-bit, 32-bit and 64-bit. Because the existing example
tpdm "tpdm@684c000" which only supports dsb sub-unit, I introduce
a new example "tpdm@6c29000" to describe the usage of this new
property.
