Subject: [PATCH v2 0/2] regulator: scmi: add support for registering SCMI regulators by name

Add support to register SCMI regulator subnodes based on an SCMI
Voltage Domain name specified via the "arm,scmi-domain-name" device
tree property.  In doing so, make the "reg" property optional with
the constraint that at least one of "reg" or "arm,scmi-domain-name"
must be specified.  If both are specified, then both must match the
Voltage Domain data exposed by the SCMI platform.

Name based SCMI regulator registration helps ensure that an SCMI
agent doesn't need to be aware of the numbering scheme used for
Voltage Domains by the SCMI platform.  It also ensures that the
correct Voltage Domain is selected for a given physical regulator.
This cannot be guaranteed with numeric Voltage Domain IDs alone.

Changes in v2:
- Replaced usage of DT property "regulator-name" with "arm,scmi-domain-name".

v1 of this patch series can be found at [1].
