dma-pool: decouple DMA_REMAP from DMA_COHERENT_POOL
DMA_REMAP is an unnecessary requirement for AMD SEV, which requires
DMA_COHERENT_POOL, so avoid selecting it when it is otherwise unnecessary.
The only other requirement for DMA coherent pools is DMA_DIRECT_REMAP, so
ensure that properly selects the config option when needed.
Fixes: 82fef0ad811f ("x86/mm: unencrypted non-blocking DMA allocations use coherent pools")
