RX-51 build of U-Boot in qemu cannot read mmc. It report error about bad
voltage. This was problem also before that commit. RX-51 Linux kernel does not
have any problem with mmc, special prepaired Maemo 5 image (with some SW on
eMMC) from Nokia working fine in qemu.

I ignored above problem in qemu, because mmc worked fine on real n900. But
after that commit mmc does not working on real n900 too.
