cleanup: Rename and move header files
Device-specific headers belong in driver/ or chip/. The include/
directory should be for common interfaces.
Code should not normally need to include driver-specific headers. If
it does, it should use the full relative path from the EC project root
(for example, drivers/charger/bq24715.h).
