Shouldnt the driver turn this on?
AFAIK there is no clock driver for the OMAP. So we have to do it before
the driver is probed.
Maybe it's time to implement it instead of piling up those hacks ?
I was thinking along the same lines at some point but then I realized
that it will make the SPL really big. And we are already tight on some
platforms like am335x.
