These clock IDs are for cmu_top, not cmu_hsi2. They were added as part
of the initial gs101/Oriole upstream support series in the following
commit
commit 0a910f1606384a5886a045e36b1fc80a7fa6706b

dt-bindings: clock: Add Google gs101 clock management unit bindings
Provide dt-schema documentation for Google gs101 SoC clock controller.
Currently this adds support for cmu_top, cmu_misc and cmu_apm.
