[Intel-gfx] [PATCH i-g-t 1/2] lib/igt_core: Move all config-related parsing to common_init_config

[Paul Kocialkowski]

This moves all the pieces related to config parsing to the dedicated
function for this purpose, renamed common_init_config for consistency.

It allows making the common_init function less big and more readable.
