I think this is being looked for all the new code introduced
in plat-omap layer for the following reasons:
Adding cpu-is-* checks makes code unmaintainable going fwd.
plat-omap layer needs to handle common code for all omap platforms.
This was raised for GPIO driver because of which, there was a
requirement to clean-up the gpio driver.
Is this stand changed? Are cpu_is* checks allowed in plat-omap?
