This patch adds checks to the checking framework to verify that node and property names contain only legal characters, and in the case of node names there is at most one '@'. At present when coming from dts input, this is mostly already ensured by the grammer, however putting the check later means its easier to generate helpful error messages rather than just "syntax error". For dtb input, these checks replace the older similar check built into flattree.c. Testcases for the checks are also implemented. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
