platform/x86: int3472: Move common.h to public includes, symbols to INTEL_INT3472

Move the common.h header file to include/linux/platform_data/x86/int3472.h
and add a "INTEL_INT3472" kernel-symbol-namespace to the exported symbols.

This is a preparation patch for exporting some more symbols for re-use in
the atomisp driver.
