The others look OK to me thanks.

Looks like the users are drivers/staging/tidspbridge and
drivers/media/rc/ir-rx51.c. Both could use platform_data pointers
for now, but that really just postpones the problem.

We can include it from <plat/dmtimer.h> for arch/arm/*omap*/*
code, but not for drivers.

We'll be keeping omap2plus_defconfig, but once we enable multiplatform
support there's really no reason to go back.
