Revert "dmaengine: Add a warning for drivers not using the generic slave caps retrieval"

Browse Source 
This reverts commit ecc19d1786.

It added a new warning to try to encourage driver writers to set the
device capabities properly, but drivers haven't been updated and in the
meantime it just generaters a scary message that users cannot actually
do anything about.

Warnings like these are appropriate if you actually expect to fix the
code that causes them.  They are not appropriate for releases.
