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).
