hwmon: (pmbus/ir38064) Add driver for Infineon IR38064 Voltage Regulator
Add the pmbus driver for the Infineon ir38064 voltage regulator.
VOUT_MODE is not supported by the device. The driver fakes linear16
mode with exponent value -8.
The device supports VOUT_PEAK, IOUT_PEAK, and TEMPERATURE_PEAK, however
this driver does not enable them.
