The hwlock-num-locks and hwlock-base-id would be common features to all
the hwspinlock drivers, so they are added as common bindings which the
individual implementations should use instead of defining their own
properties. These are added based on discussion way back on v1. You
ought to replace the "qcom,num-locks" with the first one.

I will respond to your v4 with a few comments so that we don't loose the
context in that thread.

Thanks for testing this with the new Qualcomm driver.
