[PATCH v4 2/8] hw/i2c: pmbus: add vout mode bitfields |

The VOUT_MODE command is described in the PMBus Specification,
Part II, Ver 1.3 Section 8.3
VOUT_MODE has a three bit mode and 4 bit parameter, the three bit
mode determines whether voltages are formatted as uint16, uint16,
VID, and Direct modes. VID and Direct modes use the remaining 5 bits
to scale the voltage readings.
