[PATCH i-g-t v2 23/39] lib/chamelium/v3: Log port mapping for debugging purposes

[Louis Chauvet <louis.chauvet@bootlin.com>]

Port mapping is crucial information when attempting to understand why a
test is failing, as issues may arise from incorrect mapping. This commit
adds logging of the actual port mapping to aid in debugging and problem
resolution.
