sh: mm: set VM_IOREMAP flag to the vmalloc area
Currently, for vmalloc areas with flag VM_IOREMAP set, except of the
specific alignment clamping in __get_vm_area_node(), they will be
1) Shown as ioremap in /proc/vmallocinfo;
2) Ignored by /proc/kcore reading via vread()
So for the ioremap in __sq_remap() of sh, we should set VM_IOREMAP in flag
to make it handled correctly as above.
