Subject: [PATCH] rtlwifi: Fix build errors on sh4 architecture

When rtlwifi is built for the sh4 architecture, build errors of the following
type occur. An explicit reference to <linux/io.h> should fix these. I have not
setup the cross-build environment, thus this patch is untested on that platform.
It does not cause any problems on i386 or x86_64.

John,

I'm not sure where this goes. I guess that 3.2 would be OK, unless someone
actually tries to build it on sh4. The only time I have seen the errors is
in Geert's listing of errors and warnings.
