This patch moves to use generic dt-binding for hwspinlock providers and
clients.
add #hwlock-cells for the provider and hwlocks for clients.

An unrelated question here, why the reg is same for all the child nodes
of the  parent ipc node? If this is partitioned properly, then the
driver can be simplified a bit by using platform_get_resource and
devm_ioremap_resource?

Does this need to be added for the other nodes like ns_m3_rproc@1 as well?
