Skip MMC/SDIO backport for kernels <= 2.6.23

This allows compilation of compat for 2.6.23 for builds
that do not require MMC/SDIO. Anyone interested in MMC/SDIO
backport support should look to see if its possible to
backport/add MMC/SDIO support to older kernels. That's
likeley a project on its own though, not sure.
