Currently we have one device created to handle all (maximum 2) eDMAs in the
system.
With this change all eDMA instance will have it's own device/driver.
This change is needed for further cleanups in the eDMA driver stack since
the one device/driver to handle all eDMAs in the system was not flexible
enough and prevents the upcoming work.
