swiotlb: use depends on for DMA_RESTRICTED_POOL
Use depends on instead of select for DMA_RESTRICTED_POOL; otherwise it will make SWIOTLB user configurable and cause compile errors for some arch (e.g. mips).

This enables support for restricted DMA pools which provide a level of
DMA memory protection on systems with limited hardware protection
