vdpa-sim: depend on HAS_DMA 

set_dma_ops isn't available on all architectures:

        make ARCH=um
...

   drivers/vdpa/vdpa_sim/vdpa_sim.c: In function 'vdpasim_create':
>> drivers/vdpa/vdpa_sim/vdpa_sim.c:324:2: error: implicit declaration of function 'set_dma_ops'; did you mean 'set_groups'?
+[-Werror=implicit-function-declaration]
     set_dma_ops(dev, &vdpasim_dma_ops);
     ^~~~~~~~~~~
     set_groups

Disable vdpa-sim on architectures where it isn't.
