dmaengine: remove arch dependency from DMADEVICES
dmaengine: remove arch dependency from DMADEVICES

The dependency is redundant since all drivers set their specific arch
dependencies.  The NET_DMA option is modified to be enabled only on platforms
where it is known to have a positive effect.  HAS_DMA is added as an explicit
dependency for the DMADEVICES menu.
