Although we consider am33xx device under omap34xx family of devices,
there is indeed difference between them, for example,
- Initial required mapping (->map_io)
- Early init (->init_early)
Here, the whole sequence/data is different than omap3,
For example, clock/hwmod/power/voltage data.
- clock event/source timer (name and instances)
So, this patch adds seperate machine descriptor for AM33XX family
of devices in board-generic.c file.
