These three headers are needed by drivers/gpio/gpio-da9052.c. (That file also needs a fourth header, linux/mfd/da9052/gpio.h, but maybe that's added by another patch in this series. I didn't check). That file got added by commit 07bfc91523 ("GPIO: DA9052 GPIO module v3"), and is included since v3.1.

So the DA9052 GPIO module that is currently in the mainline tree was added as unbuildable code, wasn't it?
