Add test to validate audio works before and after suspend/resume on
HDMI/DP connector.

v2: Perform a single suspend/resume for all audio combinations.
    Re-enable chamelium after suspend and separate pre-suspend
    and post-resume validation paths for clearer failure diagnostics.
v3: Drop commit and use igt_assert_f with explicit messages to
    distinguish failure in audio tests.
v4: Updated test to avoid false-pass on zero executed configs.
    Replace post-suspend forced re-enable with connector
    re-probe/connected checks.
v5: Remove unused variable and add chamelium_assert_reachable check.

Add test to validate audio works before and after suspend/resume on
HDMI/DP connector.

v2: Perform a single suspend/resume for all audio combinations.
    Re-enable chamelium after suspend and separate pre-suspend
    and post-resume validation paths for clearer failure diagnostics.
v3: Drop commit and use igt_assert_f with explicit messages to
    distinguish failure in audio tests.
v4: Removed inner igt_assert, changed from tracking execution to
    aggregating test results with success &=, so function now returns
    actual pass/fail.

Add test to validate audio works before and after suspend/resume on
HDMI/DP connector.

v2: Perform a single suspend/resume for all audio combinations.
    Re-enable chamelium after suspend and separate pre-suspend
    and post-resume validation paths for clearer failure diagnostics.
