x86/dma: Use DMA-direct (CONFIG_DMA_DIRECT_OPS=y)
The generic DMA-direct (CONFIG_DMA_DIRECT_OPS=y) implementation is now functionally equivalent to the x86 nommu dma_map implementation, so switch over to using it. That includes switching from using x86_dma_supported in various IOMMU drivers to use dma_direct_supported instead, which provides the same functionality.
