omap3_logic: Add Device Tree Support and more DM drivers

This patch also removes all the excessive code for NS16550 intiailization
as the device tree can do that now.  This also adds DM_I2C and DM_MMC
since the overlying drivers have the built-in support already.  The
corresponding include/config/omap3_logic.h also reduced in size
due to the new device tree support.

  Retain Auto-detect ability between SOM-LV and Torpedo
  Split this off from the device sub submissions

+Summary
+=======
+
+The source for omap3som encompases the DM3730 SOM-LV and DM3730 Torpedo platforms.
+
+By default, the Torpedo Device Tree is integrated into U-Boot,but the MMC controller, GPIO and I2C controllers are the same, so for the purposes of loading U-Boot, it should be sufficient.  However this will display the Model as "LogicPD Zoom DM3730 Torpedo + Wireless Development Kit" upon boot.
+
+The actual board remains autodetected and the Board will read "DM37xx SOM LV" when used on the DM37 SOM-LV.  The device tree loaded with Linux is also correct.
+
+Integrating the SOM-LV Device Tree into U-Boot
+==============================================
+
+This step is optional, but should you want to change the default to the SOM-LV, locate the configs/omap3_logic_defconfig file and make the following change.
+
+  CONFIG_DEFAULT_DEVICE_TREE="logicpd-som-lv-37xx-devkit"
+
+  make distclean
+  make omap3_logic_defconfig
