Yes that seems to be the case.

If we get rid of the system timer dependency to hwmod we can
pretty much initialize everything later on and don't need to
use early_init stuff at all.

I'm currently thinking that we should just have omap[234]_init_timer
functions that do not depend on hwmod at all.

That seems like a good to fix for now until the hwmod timer
changes are sorted out.
