[PATCH v3 2/2] coresight-tpda: Change qcom,dsb-element-size to qcom,dsb-elem-bits

[Mao Jinlong]

Change qcom,dsb-element-size to qcom,dsb-elem-bits as the unit is bit.
When use "-bits" suffix, the type of the property is u32 from
property-units.yaml, so use fwnode_property_read_u32 to read the
property.

Fixes: 57e7235aa1d1 ("coresight-tpda: Add DSB dataset support")
