Cleanup old headers and namespace declarations

Remove the header includes for the old phosphor::logging::log API
as well as unnecessary phosphor::logging namespace declarations.
Fully qualify phosphor::logging namespace where applicable and/or
needed.

Tested:
* Verified commit passed CI unit tests.
* Verified commit built using bitbake.
