[media] bdisp: prevent compiling on random arch

This driver requires support for DMA attrs function, and not
just DMA. Change the options accordingly to remove those errors:

  base = dma_alloc_attrs(dev, size, &paddr, GFP_KERNEL | GFP_DMA, &attrs);

Also, get rid of bogus, unused and duplicated symbol declaration
for the config option done at bdisp/Kconfig.
