Move phosphor-power-supply to lg2

Update the logging API used for files in phosphor-power-supply
from the older phosphor::logging::log style of journal traces
to the newer lg2::log style.

Tested:
* Verified journal traces worked correctly in simulation.
* Verified that formatting and key-value pairs for the
  messages were correct via the journalctl command output.
