The cpufreq-cpu0 driver changes to instantiate use platform_driver
mechanism. The patch is an am33xx platform level adaptation for it.

Hi Shawn,
I have tested your patch on AM335x-EVM, no issues observed.
I think, better post v3 version which contains this patch
and cpu0-cpufreq driver changes.
Or
Post v3 of cpufreq-cpu0 driver changes.
Thanks
AnilKumar
