mfd: bq257xx: Add BQ25792 support
Add register definitions and a new 'type' enum to be passed via MFD
private data to support the BQ25792, which is a newer variant of the
BQ257xx family.
BQ25792 shares similar logic of operation with the already supported
BQ25703A but has a completely different register map and different
electrical constraints.
