[PATCH] image: fdt: check "status" of "/reserved-memory" subnodes

boot_fdt_add_mem_rsv_regions() scans the subnodes of "/reserved-memory" and adds them to reserved lmb regions. Currently this scanning does not take into "status" property. Even if the subnode is disabled, it gets added to the reserved lmb regions.
This patch checks the "status" property before adding it to reserved lmb regions.

Thank You Simon for the review.
May I know what are the next steps in making forward progress on this?

The patch is in my queue but I've had some test failures. Assuming it is not the culprit I expect it will be applied by next week.
