[RFC PATCH v1 1/3] image: allow setting FIT compatible per device

[Phil Taylor]

The FIT generation helper already accepts a compatible string, but the
image recipes cannot pass one on a per-device basis.

Add DEVICE_FIT_COMPATIBLE and forward it to mkits.sh. This allows devices
with bootloaders that use FIT compatible matching to describe the board
without replacing the common FIT recipe.
