sh: Bump up dma_ops initialization far earlier in the boot process.
Presently this was tacked on to the dma debug init bits from fs_initcall(), which is far too late for devices setting up their own per-device coherent areas. Throw this in the beginning of mem_init(), as per the x86 iommu allocation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
