MI424WR - add rev D support

Add support for revision D of the MI424WR. Rev D swaps LAN & WAN ports so this patch maintains eth0 for LAN and eth1 for WAN. For details on rev D usage, see http://wiki.openwrt.org/toh/actiontec/mi424wr Signed-off-by: Jose Vasconcellos <jvasco@verizon.net> SVN-Revision: 32820
