[RFC PATCH 2/5] fwu: Add the fwu-mdata node for removal from devicetree

[Sughosh Ganu]

The FWU metadata devicetree node points to the device which stores the
metadata structure. This node is relevant only in U-Boot, and is not
to be passed to the OS. Register for purging this node from the
devicetree, before passing it to the OS.
