Currently, Vybrid's sdboot variable tries to load the kernel from /boot of the root partition (typically second partition when using the sdcard image). However, since we moved to flash the kernel in a separate UBI volume, we no longer deploy the kernel/device tree to /boot, hence sdboot does not work in its current state. Load the kernel and device tree from the first (typically FAT) partition as customary on all Toradex modules. While at it also change from rw to ro as e.g. systemd will re-mount the root file system rw anyway after checking it.
