hwmon: (pmbus) Let PMBus drivers report the supported PMBus revision

Browse source

Some PMBus chips do not support the PMBUS_REVISION command. Knowing
the PMBUs revision supported by a chip is relevant for PMBUs core
functionality, so add support for letting chip drivers report the PMBUs
revision.

Use the new capability to report the PMBus revision supported by MAX20830.

While at it, add definitions for PMBUs revisons 1.3.1 and 1.4.
