So this begs the question, why does AM33xx return true from 
cpu_is_omap34xx() is the architecture is based upon OMAP4 and not OMAP3?

I understand it is a Cortex-A8 versus Corex-A9, but if the architecture 
is closer to OMAP4, then should it not be classed as OMAP4 and not OMAP3?

Raises another question if we should really have arch_is_omapXXXX and 
not cpu_is_omapXXXX.
