bq274xx sensor - Fails to compile when CONFIG_PM_DEVICE enabled

[ballardr]

Describe the bug
When using the bq274xx sensor (kconfigs: CONFIG_SENSOR=y; CONFIG_BQ274XX=y), in conjunction with kconfig CONFIG_PM_DEVICE, the bq274xx sensor module fails to compile as on line 652 of zephyr/drivers/sensor/bq274xx/bq274xx.c, it tries to access the struct member "pm_state" of bq274xx which is of type "struct bq274xx_data" (as per line 414). However in zephyr/drivers/sensor/bq274xx/bq274xx.h it can be seen this structure has no pm_state member.

** ***** NOTE: I submitted this earlier (#39712), but it got closed with a fix that is completely unrelated and does not fix the the structure as per the logs and console section below. gmarull, please read the bug before closing immaturely ***** **

To Reproduce
Enable the following kconfigs:
CONFIG_SENSOR=y
CONFIG_BQ274XX=y
CONFIG_PM=y
CONFIG_PM_DEVICE=y

Expected behavior
The code in question is designed to make sure the sensor is powered

Impact
Fails to compile

Logs and console output

** Work around **
For the time being, I'm commenting out lines 651 to 653 of zephyr/drivers/sensor/bq274xx/bq274xx.c
