config-tools: bring all cores online

Browse Source 
Bring all the cores up in the beginning of the board_inspector.py
It is expected to run board_inspector in clean and native environment.
To resolve the issue that user may run other jobs which puts cores
offline, bringing up all cores online so tool can run cpuid to extract
all available cores information.
