[PATCH igt 2/2] tools/msm_dp_compliance: Add arg to specify connector name

[Rob Clark <robdclark@gmail.com>]

From: Rob Clark <robdclark@chromium.org>

To support multiple DP connectors, the debugfs files will be moving into
a per-connector subdirectory in debugfs.  So add an arg to specify the
appropriate connector name.
