The patch, following the suggestion expressed in the review [1] for the
stm32f746-disco board support, moves the Linux kernel and the related
device tree to the ext4 rootfs partition. By doing so, the vfat partition,
improperly called u-boot, no longer makes sense and can therefore be
removed. From now on, U-Boot will load the kernel and the device tree
from the ext4 rootfs partition.
