Logic PD AM37/DM37 has used the generic omap3_logic files, but
with all the device tree entries, pinctrl and DM now integrated,
this patch splits the AM/DM37 SOM-LV into its own board so it can
make use of all the pins and hardware correctly.

With there now being four device tree files, and 4 separate
defconfig files, the code necessary to determine which board is
being used is no longer necessary as the corresponding pin-muxing
and board names are determined by the device tree.
