The approach taken in this patch is, AM33XX device will be considered as OMAP3 variant, and a separate SoC class created for AM33XX family of devices with a subclass type for AM335X device which is newly added device in the family. This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x() checks will return success on AM335X. A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3 to include support for AM33XX build.
