power: regulator: scmi: Move regulator subnode hack to scmi_regulator
The current code attempts to bind scmi_voltage_domain to regulator subnode
of the SCMI protocol node, so scmi_voltage_domain can then bind regulators
directly to subnodes of its node. This kind of behavior should not be in
core code, move it into scmi_voltage_domain driver code. Let the driver
descend into regulator node and bind regulators to its subnodes.
