regulator: scmi: Allow for zero voltage domains
SCMI Voltage protocol allows the platform to report no voltage domains
on discovery, while warning the user about such an odd configuration.
As a consequence this condition should not be treated as error by the SCMI
regulator driver either.
Allow SCMI regulator driver to probe successfully even when no voltage
domains are discovered.
