[PATCH 2/4] reset: Add sandbox tests for reset_reset() and reset_reset_bulk()

[Michal Simek]

Add DM test coverage for the new reset_reset() and reset_reset_bulk()
API functions. The tests exercise the assert + deassert fallback path
since the sandbox reset driver does not implement the rst_reset op.
