[PATCH v2 08/12] test: dm: simplify SCMI unit test on sandbox
AKASHI Takahiro

Wed Jul 26 10:38:04 CEST 2023
Adding SCMI base protocol makes it inconvenient to hold the agent instance
(udevice) locally since the agent device will be re-created per each test.
Just remove it and simplify the test flows.
The test scenario is not changed at all.
