ARM: dts: omap3-evm: Enable DM and devicetree for TMDSEVM{3530, 3730}

This commit updates the configuration files needed to support OF_CONTROL
on the OMAP3 EVM baseboard.

Additionally:
- CONFIG_SYS_THUMB_BUILD is enabled
- CONFIG_SPL_ENV_SUPPORT is enabled

Tested using GCC 7.2.0 [--with-float=hard --with-mode=thumb].
