dma-direct: use __DMA_ATTR_ALLOC_CC_SHARED in alloc/free paths

Propagate force_dma_unencrypted() into __DMA_ATTR_ALLOC_CC_SHARED in the
dma-direct allocation path and use the attribute to drive the related
decisions.

This updates dma_direct_alloc(), dma_direct_free(), and
dma_direct_alloc_pages() to fold the forced unencrypted case into attrs.
