pHAL: Enabled environment variable based pHAL logging

pHAL repos logging level is initialised based on repository
specific environment variables. If the environment variable
is not set by the user, default logging level ( INFO only)
will be getting initialised.

Environment variable names:
 - PDBG_LOG pdbg library
 - IPL_LOG  ipl library
 - LIBEKB_LOG libekb library

Refer individual repository for logging level details.

Example: To set pdbg log level to PDBG_DEBUG
  export PDBG_LOG=4
  systemctl import-environment PDBG_LOG
