Remove bogus errors from check_chosen.

It is not an error for /chosen (or any of its children) to be missing.

It is not a requirement that the output of dtc be a complete, valid
device tree, as it may be intended that the dtb be passed through boot
code that will complete it.  Thus, do not complain.
