This patch series restricts LOBF test execution based on the observed 
support behavior across eDP and DP 2.1 configurations.
From our analysis, LOBF is supported on both eDP and DP 2.1 
only when the display version is > 35. For display versions between 20-35, 
LOBF support is limited to eDP. Additionally, either Aux-less or Aux-wake 
mode must be enabled for LOBF execution.

LOBF support may also depend on the eDP version 
(e.g., valid only for eDP ≥ 1.5). Confirming this would require reading 
DPCD registers via IGT, which is not preferred at this stage. To avoid 
unintended failures and ensure proper skip behavior on unsupported 
connectors, the test is now restricted to execute only when Aux-less mode 
is enabled, preventing false negatives and improving stability.
