fdt_region: Check for a single root node of the correct name
At present fdt_find_regions() assumes that the FIT is a valid devicetree.
If the FIT has two root nodes this is currently not detected in this
function, nor does libfdt's fdt_check_full() notice. Also it is possible
for the root node to have a name even though it should not.
Add checks for these and return -FDT_ERR_BADSTRUCTURE if a problem is
detected.
