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:
---8<---
Loading file "/boot/uImage" from mmc device 0:1
1830666 bytes read in 1293 ms (1.3 MiB/s)
--->8---

vs.

---8<---
Loading file "/boot/uImage" from mmc device 0:1
1830666 bytes read in 237 ms (7.4 MiB/s)
--->8---

Commit 1db7377a70a8d931c32648e717695133120d5456 is currently in
u-boot-atmel/master and may need some time to hit the u-boot-avr32/master. If
someone want to test it cherry pick the commit from u-boot-atmel/master.
