[igt-dev] [PATCH] igt_chameleon: Assert if there are no connected ports

[Mark Yacoub]

[Why]
The tests are meant to run on devices that have a chameleon connected.
If autodiscovery finds no port, it means something is off and the DUT is
not behaving well.

[How]
Add an assert if no port is mapped.
