[meta-freescale] [meta-fsl-arm PATCH 2/3] image_types_fsl.bbclass: Fail if a Device Tree file is missing

[Otavio Salvador]

When generating the rootfs we need to include all the referenced
Device Tree files. The code were gracefully checking if the file
existed before building the image however the expected behavior is to
fail.

As consequence of this change, if someone is using a very old kernel
(no Device Tree based) and tries to generate an image, it will fail
until the machine definition is changed to not list Device Tree files
for installation.

Currently all machines supported by meta-fsl-arm BSP are consistent
for the default kernel in use however custom BSP may need to be
changed accordingly.
