riscv: Only initialize swiotlb when necessary The SWIOTLB buffer is not needed unless the physical address space is beyond the limit of dma, only initialize swiotlb when swiotlb_force is true or not all system memory is DMA-able. Also move the swiotlb_init() into mem_init(). Signed-off-by: Kefeng Wang <wangkefeng.wang@huawei.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>
