Changes in v2:
- don't test IS_ENABLED(CONFIG_DM_REGULATOR_SCMI) in test
Add local variables agent0/agent1 to refer to SCMI sandbox context
agent and ease readability of the test.
For consistency, rename regul_dev to regul0_dev and remove sandbox_voltd
in dm_test_scmi_voltage_domains().

Fix inline comments and empty line in scmi driver and test files.
Remove test on IS_ENABLED(CONFIG_*_SCMI) in test/dm/scmi.c since these
configuration are expected enabled when CONFIG_FIRMWARE_SCMI is enabled
in sandbox configuration.
