ps3: Fix black and white stripes
Fix the black and white stripes issue with WUXGA monitor via HDMI.
It seems that when we use a VESA resolution from boot up, the AV settings
driver could not be initialized correctly. In that case we need a dummy
packet before VESA setting.
[Geert] Refactored to reduce code duplication.
