smc91x: SMC_IO_SHIFT platform data support for default case

Commit 159198862adad7109bb347bb30a620f67beac45f added SMC_IO_SHIFT
platform data support. After that ARM board support was added.

The default case is still missing though, so on SuperH SMC_IO_SHIFT
is constantly zero regardless of what you pass as platform data.
