It'd be interesting to know if this is strictly required for the driver
to work properly. The call to intel_soc_pmic_exec_mipi_pmic_seq_element
has some error handling after it, maybe that should just be surrounded
by an #ifdef or IS_ENABLED for PMIC_OPREGION, like some other drivers
do.

Regardless of that:
