colibri_vf: fix sdboot for vybrid modules

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.

apalis_imx6: add distroboot support

Add support for distro boot. This is especially helpful for external
devices. There is a global boot command which scans a predefined
list of boot targets:
  run distro_bootcmd

As well as direct boot commands such as:
  run bootcmd_mmc1
  run bootcmd_mmc2
  run bootcmd_usb
  run bootcmd_dhcp
  ...

Refer to doc/README.distro for details.

While at it, remove the CONFIG_DRIVE_TYPES define which has not
been used and was meant to be used for multi device boot support
which is now provided by distroboot.
