Update to get PSU Asset information from parsing JSON file

The purpose is to support multiple PMBus device drivers, so need to
flexibly read the required PSU asset information attribute from the
configuration file (/usr/share/phosphor-power/psu.json)
and update D-BUS.

Tested: Update phosphor-power_git.bb and add the
psu.json. The psu-monitor process runs normally and can obtain the
asset information of PSU via D-BUS and REST command.
