swiotlb: Add swiotlb_free() function
swiotlb_free() function frees all allocated memory for swiotlb. We need to initialize swiotlb before IOMMU initialization (x86 and powerpc needs to allocate memory from bootmem allocator). If IOMMU initialization is successful, we need to free swiotlb resource (don't want to waste 64MB).
