[PATCH 5/5] dmaengine: owl-dma: fix kernel-doc style for enum

[Vinod Koul]

Driver doesn't use keyword enum for enum owl_dmadesc_offsets resulting
in warning:

drivers/dma/owl-dma.c:139: warning: cannot understand function prototype:
'enum owl_dmadesc_offsets '

So add the keyword to fix it and also add documentation for missing
OWL_DMADESC_SIZE
