MIPS: Add __ioread64_copy
We currently have __ioread32_copy, __iowrite32_copy & __iowrite64_copy
helpers in lib/iomap_copy.c. This patch adds __ioread64_copy to round
out the set, allowing copies from I/O memory using 32 or 64 bit reads.
[ralf@linux-mips.org: Changed to move all the code of this patch to be
applied to arch/mips temporarily.]
