Add a test for the correct device removal. Currently two different ways for device removal are supported:
- Normal device removal via the device_remove() API - Removal via selective device driver flags (DM_FLAG_ACTIVE_DMA)
This new test "remove_active_dma" adds tests cases for those both ways of removal.
