mfd: bq257xx: Mark self-modifying BQ25792 registers volatile
Some BQ25792 configuration registers change without being written: input
source detection sets VINDPM and IINDPM at plug-in, plug-in also clears
EN_HIZ, the FORCE_* bits clear once their operation starts or completes,
EN_ACDRV1/2 follow input path changes, and ADC_EN clears after a one-shot
conversion. Reading them from the cache returns stale values.
Mark these registers volatile, keeping the cache for the rest.
