dmaengine: ep93xx_dma: Provide some missing struct attribute documentation

A couple of entries were missed, causing kerneldoc to complain.

Fixes the following W=1 kernel build warning(s):

 drivers/dma/ep93xx_dma.c:183: warning: Function parameter or member 'slave_config' not described in 'ep93xx_dma_chan'
 drivers/dma/ep93xx_dma.c:215: warning: Function parameter or member 'hw_synchronize' not described in 'ep93xx_dma_engine'
