sfc: Use __iowrite64_copy instead of a slightly different local function
__iowrite64_copy() isn't quite the same as efx_memcpy_64(), but
it looks close enough:
- The length is in units of qwords not bytes
- It never byte-swaps, but that doesn't make a difference now as PIO
is only enabled for x86_64
- It doesn't include any memory barriers, but that's OK as there is a
barrier just before pushing the doorbell
- mlx4_en uses it for the same purpose
Compile-tested only.
