Currently only the primary CPU in the CA15 cluster has a clocks
property, while the secondary CPU core is driven by the same clock.
Add the missing clocks property to fix this.

Thanks,
I have applied the above for v4.15. There was some fuzz when applying the
r8a7790 patches so please check that what I have is correct after I push
the next branch of the renesas tree a little later day.
