As unit of dsb element size is bit, change qcom,dsb-element-size to qcom,dsb-elem-bits. And CMB uses -bits suffix as well. There is no TPDM node in any DT now. Make such change before any TPDM node is added to DT.
Change since V1: 1. Update the commit message for dt-binding. 2. Fix the dt_binding_check error for dt-binding change.

Change qcom,dsb-element-size to qcom,dsb-element-bits as the unit is bit. There is no tpdm node in any DT as of now. Make this change before any tpdm node is added to DT.
