Subject: [PATCH] ARM: dts: omap3/omap35 Torpedo and SOM-LV: Unify and shrink
 SPL dtb

None of these boards boot, but the solution appears to be the same.
All the boards have SPL that is too large.  With a few defconfig
options removed, these corresponding options can be removed from
their respective SPL dtb files.

This patch unifies the DM37/OMAP35 boards' -u-boot.dtsi files
to remove gpio's, i2c, bandgap, thermal zones, unneeded uarts, and
unneeded MMC nodes.
