[PATCH] ARM: omap3_logic boards: Convert to DM_ETH

With the converstion of SMC911x to DM, this can facilitate the omap3
boards from LogicPD (now called Beacon EmbeddedWorks) to be converted.
There isn't a clean solution to doing this in phases, so the boards are
all being done together to avoid breaking functionality.
Because the GPMC bus hasn't been converted, the -u-boot.dtsi node needs
to show the address of the ethernet controller for each board.
The board file, which is common betwen the OMAP35 and DM37 SOM LV and
Torpedo boards, can remove the manual ethernet initialization, but it
still needs to register the address and GPMC configuration for the Ethernet
controller which is now being moved around to board_late_init().
Lastly, this patch updates the various config files to add the reference
for DM_ETH and remove the SMC address, which is now fetched from the
newly created device tree nodes.
