qoriq: set compat_version in board.d

Currently, sysupgrade without the -n option complains:

  # sysupgrade -v tmp/openwrt-qoriq-generic-watchguard_firebox-m300-squashfs-sysupgrade.img.gz
  upgrade: The device is supported, but the config is incompatible to the new image (1.0->1.1). Please upgrade without keeping config (sysupgrade -n).
  upgrade: Kernel switched to FIT uImage. Update U-Boot environment.
  upgrade: Reading partition table from bootdisk...
  upgrade: Extract boot sector from the image
  upgrade: Reading partition table from image...
  Image check failed.

So, add the missing 05_compat-version to /etc/board.d/ to allow
sysupgrade to save config without using -f.
