Commit 2d3de197a818 ("ARM: dts: arm: Update ICST clock nodes 'reg' and node names") moved to using generic node names. That results in trying to register multiple clocks with the same name. Fix this by including the unit-address in the clock name.

This should be applied to stable to minimize DT ABI breakage.
