ARM: OMAP2+: Remove legacy booting support for LogicPD Torpedo
We've been moving all omap2+ based systems to boot in device tree only mode for a few years now. Only omap3 has legacy booting support remaining. Most omap3 boards already have related arch/arm/boot/*.dts* files for booting with device tree. This board has support for device tree based booting, and we've been printing warnings about the legacy booting being deprecated for a few merge cycles now. Let's attempt to remove the legacy booting for it. The reason for removing the legacy booting support now rather than later is we can simply revert this patch if necessary if we run into some unexpected issues that are not trivial to fix for the device tree based booting.
