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. This is done by adding a new test driver, which has this flag set. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Simon Glass <sjg@chromium.org>
