Add CPU performance profiles
Update makefiles for new build methods

Move prebuilt files to recovery/root so they are automatically copied by
recovery_root_private (no need for PRODUCT_COPY_FILES or prebuilt
modules).

Add chargeled under TARGET_RECOVERY_DEVICE_MODULES so that it becomes a
dependency of recovery.
