hwmon: (pmbus/adm1266) add firmware_revision debugfs entry
The ADM1266 reports its firmware revision via the IC_DEVICE_REV
manufacturer-specific block-read command (0xAE, datasheet Rev. D
Table 80). The first three returned bytes are the firmware
major.minor.patch fields. This is useful when correlating field
behaviour against ADI release notes; expose it through debugfs
alongside the existing sequencer_state entry.
The standard PMBus MFR_REVISION (0x9B) register is already exposed
by pmbus_core's debugfs auto-create path and reports the
manufacturer revision, which is a separate thing from the firmware
running on the device.
