Hmm the build does not break for me?

Let's rather fix whatever the issue is for booting (or building?)
omap4 with CONFIG_PM and CONFIG_PM_RUNTIME. If we can't implement
PM yet for omap4, we can just return early if cpu_is_omap44xx.

CONFIG_SMP we can't enable as that requires various ARM changes
to work on unicore systems. But hopefully we can enable that too
at some point with select SMP if ARCH_OMAP4.
