[Intel-gfx] [PATCH 1/3] drm/i915: fix the incorrect condition judgement in dp_is_present_in_vbt

[yakui.zhao at intel.com]

From: Zhao Yakui <yakui.zhao at intel.com>

The condition judgement is wrong in the function of dp_is_present_in_vbt, which
will cause that we can't setup display port correctly.
Fix the error condition judgement.
