  Enable the xilinx dmaengine driver on RISC-V platform. We have verified
the CDMA on RISC-V platform, enable this configuration to allow build on
RISC-V.

Hi Palmer,
Thanks for your review.

Hi Vinod,
Could I know if this patch also meets your expectations? If it does,
would you please consider accepting it?
Thanks.

Instead of adding one more dependency I think we can cleanup this 
dependency list. Similar changes done in ethernet subsystem. Please 
have a look at below commits:

e8b6c54f6d57 net: xilinx: temac: Relax Kconfig dependencies
d7eaf962a90b net: axienet: In kconfig remove arch dependency for axi_emac
