dmaengine: xilinx: dma: remove arch dependency

As following patches, xilinx dma is also now architecture agnostic,
and it can be compiled for several architectures. We have verified the
CDMA on RISC-V platform, let's remove the ARCH dependency list instead
of adding new ARCH.

To avoid breaking the s390 build, add a dependency on HAS_IOMEM.
