power-utils: Retrieve Firmware Version from sysfs

Added support to retrieve firmware version from sysfs. This required the
following code additions and modifications:

1 - Locate the target PSU object and retrieve 'i2cBus' and 'i2cAddress'.
2 - Obtain PMBus interface access.
3 - Read the firmware version from sysfs.

Tested:
  The new code was loaded onto a system, and the firmware version was
  successfully read from sysfs. Verified getVersion using psu.json file
  did not change.
