ARM: OMAP2+: Warn about deprecated legacy booting mode
We're moving omaps to use device tree based booting and already have omap2, omap4, omap5, am335x and am437x booting in device tree only mode. Only omap3 still has legacy booting still around and we really want to make that device tree only. So let's add a warning about deprecated legacy booting so we get people to upgrade their boards to use device tree based booting and find out about any remaining issues. Note that for most boards we already have the .dts file and those can be booted with without changing the bootloader using the appended DTB mode.
