I don't think this needs to be SoC specific, we can add multiple
DT_MACHINE_START entries into a single file. So it should be
just board-omap-dt.c.

This has changed, see the cleanup branch. Also, let's just leave
out the sdram timings for now as we can work with bootloader
timings until those come from DT too.

Most likely we just need SoC specific init functions in this file
now until the mux data comes from DT also.

Here omap3_init_early is now generic in the cleanup branch.
