Why don't we continue the effort to remove "struct page" entirely

IMHO, everything not exposed to DMA API users should use
phys_addr_t, including the DMA address pool.

The alloc interfaces return a struct page, that is why this stuff is
organized like this. Look at dma_alloc_pages()

There is also an API that forms a scatterlist that has to be struct
page as well
