Are you referring to a scenario where removal of an explicit 
initialization of PCA9450_RESET_CTRL in favor of the setup in the driver 
would lead to an unitialized PCA9450_RESET_CTRL if the driver is not 
enabled?

For the imx93 boards, behaviour remains unchanged same as those two 
boards configure PCA9450_RESET_CTRL in pca9450_register_init_callback, 
which is called by the driver. So change in behavior with those.

Not so on the imx8 boards where pmic_configure is called unconditionally 
in the power-on routine.

Given this, I'm not sure if we should remove the explicit register 
config for the imx8 boards as Ahmad mentioned. I think I remember Sasha 
mentioning a reason why board kconfig doesn't select the pmic driver?..
