Dmatest is a standalone kernel module intended for stress testing DMA 
engines from userspace with N number of threads and M size combinations etc.

This one; on the other hand, is selftest to verify hardware is working 
as expected during power up.

Almost all DMA engine drivers come with some sort of selftest code 
called from probe. I followed the same design pattern.

I think the goal is to remove the duplicate self test code in all 
drivers over time.
