dmaengine: fsldma: declare slave capabilities for the generic code
Since commit ecc19d17868b ("dmaengine: Add a warning for drivers not
using the generic slave caps retrieval"), the dma drivers are required
to fill the caps infos in order to support generic slaves caps
retrieval. Otherwise we will get a warning like this:
WARNING: at drivers/dma/dmaengine.c:830
