Looking at it closer, I have the feeling that you want to do similar to
devm_gpio_request() in linux/gpio.h :

In linux/mutex.h, add a prototype for devm_mutex_init() when
CONFIG_DEBUG_MUTEXES is defined and an empty static inline otherwise.
Then define devm_mutex_init() in kernel/locking/mutex-debug.c

Yes, this would be almost perfect decision. BTW just as in linux/gpio.h
we wouldn't have to include whole "linux/device.h" into mutex.h, only
add forward declaration of struct device;

In case you place it into a C-file. Otherwise you need a header for
the API and that is not acceptable for mutex.h.
