ArmPlatformPkg/Bds: Fixed adding support for new boot entry when the generated DevicePath is bigger than one node 

The initial support was only considering the added Device Path will be a single node.
TFTP for instance requires two new nodes on the top of the ethernet Device Path; a first
one for the IP address of the server and a second one for the file to download.

This change replace the return argument from a DevicePath node by a DevicePath.
It means the End Device Path node is now required.
