Fix kconfig warnings & build errors caused by DRM_ZYNQMP_DPSUB.
Any driver that selects DMA_ENGINE should make sure that DMADEVICES is already enabled. As is, this causes build errors in many other drivers.
See https://lore.kernel.org/lkml/202009020239.oUPh82Xc%25lkp@intel.com/ for the numerous build errors.
WARNING: unmet direct dependencies detected for DMA_ENGINE Depends on [n]: DMADEVICES [=n] Selected by [y]:

Sorry, this is a duplicate of a patch that Laurent has already posted so my patch isn't needed.
