Remove some unnecessary plat/ includes that are interfering with multi-subarch
ARM kernels.

Still awaiting some final testing here.  Rafael, was wondering if you 
would be willing to ack this so we can merge it via the OMAP tree?   
Otherwise the patch can be split into an OMAP part and a CPUFreq part that 
can go in across two merge windows.

Hmm.
I did similar change[1] a while back. Kevin didn't like idea though
that point of time.

I was wrong.

At the time, we were thinking about how to get rid of clkdev nodes
instead of add more.  Now, we need to clean up these drivers and this is
the only way to do it, so I retract my objection.

Thanks Rafael.  Looks like you've got "cpufreq: OMAP: Check IS_ERR() 
instead of NULL for omap_device_get_by_hwmod_name" queued which conflicts 
with this patch, so will just queue the arch/arm/mach-omap2/ changes for 
now.  Then the drivers/cpufreq/omap-cpufreq.c part can go in during 3.8.

- Paul
