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.
