PATCH 1/1 avr32: allow multi block mmc access for all boards

Commit 1db7377a70a8d931c32648e717695133120d5456 fixes the gen_atmel_mci driver to be able to use multi block access for avr32. Therefore remove the setting which forces single block access.

This also adds a huge performace gain for mmc access:
