pwm: pca9685: clarify pca9685_set_sleep_mode() interface.
The function
static void pca9685_set_sleep_mode(struct pca9685 *pca, int sleep)
takes the chip in and out of sleep mode, depending on the value of
sleep, which is interpreted as a boolean.
To clarify that 'int sleep' is a boolean and not a sleep delay,
change the function interface to:
static void pca9685_set_sleep_mode(struct pca9685 *pca, bool enable)
