Remove the last two legacy board-*.c files for omap3 for legacy 

booting for v4.8 to allow making mach-omap2 device tree only for
 v4.9.
 
 We've had Nokia N900 and omap3 LDP board-*.c files remaining
 while other omap3 devices have been device tree only for quite
 a while now. Also N900 and LDP have had device tree based booting
 working for years now, but few drivers for N900 were still only
 working in legacy only mode until recently. With the remaining
 issues out of the way, we discussed on the mailing lists that
 we're finally OK to remove the remaining board-*.c files.
 
 For the timing of this pull request, I wanted to wait until
 v4.8-rc1 is out to make sure the legacy booting still works fine
 after the merge window before doing it.
 
 And for v4.8, let's not touch any other platform data in case we
 still need to revert for some reason. This makes the revert just a
 question of adding back the legacy board-*.c files.
 
 Then if no issues, we can remove the unused remaining platform
 data later on for v4.9.

Merge tag 'omap-for-v4.8/legacy-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

Merge "drop last omap3 board files for v4.8" from Tony Lindgren:

Remove the last two legacy board-*.c files for omap3 for legacy
booting for v4.8 to allow making mach-omap2 device tree only for
v4.9.

We've had Nokia N900 and omap3 LDP board-*.c files remaining
while other omap3 devices have been device tree only for quite
a while now. Also N900 and LDP have had device tree based booting
working for years now, but few drivers for N900 were still only
working in legacy only mode until recently. With the remaining
issues out of the way, we discussed on the mailing lists that
we're finally OK to remove the remaining board-*.c files.

For the timing of this pull request, I wanted to wait until
v4.8-rc1 is out to make sure the legacy booting still works fine
after the merge window before doing it.

And for v4.8, let's not touch any other platform data in case we
still need to revert for some reason. This makes the revert just a
question of adding back the legacy board-*.c files.

Then if no issues, we can remove the unused remaining platform
data later on for v4.9.
