Previously, <linux/module.h> was included before ralink_regs.h in all

After commit 26dd3e4ff9ac ("MIPS: Audit and remove any unnecessary
uses of module.h") removed the inclusion of module.h from multiple
places, some ralink platforms failed to build with the following error:

Fix this by including <linux/io.h>.

Looks sensible, applied.  But I'm wondering why I don't see this in my
test builds.

Thanks for merging them. There isn't currently a defconfig for this 
platform, but I am working on adding one.
