[igt-dev] [PATCH i-g-t] tests/kms_chamelium: check ports have audio support

[Simon Ser <simon.ser@intel.com>]

Before starting an audio test, make sure the Chamelium supports audio capture
on the port we want to use.

Old Chamelium devices don't support audio capture on DisplayPort ports. This
patch will make the tests skip DisplayPort ports.
