Teach dma_capable() about DMA_ATTR_CC_SHARED so the capability check can reject encrypted DMA addresses for devices that require unencrypted/shared DMA. Also propagate DMA_ATTR_CC_SHARED in swiotlb_map() when the selected SWIOTLB pool is decrypted so the capability check sees the correct DMA address attribute.
