Here is the list of items of code cleanup 1. Define TCO registers in smbus.h and not in pmc.h (as per EDS). 2. Include smbus.h wherever these TCO register defines were used. 3. Remove duplication of define in gpio_defs.h. 4. Remove unnecessary console.h include from memmap.h as no prints done. 5. Remove unnecessary comment from pch.c. BUG=none BRANCH=none TEST=Built and boot kunimitsu.
