smegw01: Allow booting the Yocto image by default

On the Yocto image there is a single partition and the kernel
and dtb are present in the 'boot' directory.

Change it accordingly so that the board can boot the Yocto
image by default.

Use the generic 'load' command instead, which is able to
read from an ext4 partition.
