Add tests for SCMI clocks. A test device driver sandbox-scmi_devices.c is used to get clock resources, allowing further clock manipulation.
Change sandbox-smci_agent to emulate 3 clocks exposed through 2 agents. Add DM test scmi_clocks to test these 3 clocks. Update DM test sandbox_scmi_agent with load/remove test sequences factorized by {load|remove}_sandbox_scmi_test_devices() helper functions.

Changes in v4:
- Move SCMI test devices instances from BSS to test device private data and update test/dm/scmi.c accordingly.
- Update sandbox_scmi_devices_ctx() helper to add device reference arg.
- Fix spelling issues in inline comments.
- Rename local variables rc to ret for consistency.
Changes in v3:
- New commit in the series, addresses review comments on test support. ut_dm_scmi_clocks test SCMI are found and behave as expected for the implemented clk uclass methods.
