ARM: OMAP3: Remove cm-t3517 legacy support
This board is working with device tree based booting so there should not be any need to keep the legacy booting support around. People using this board can boot it with appended DTB with existing bootloader. By removing the 3517 legacy booting support we can get a bit closer to making all of omap3 boot in device tree only mode.
