At IAFW side, the framebuffer resolution is 608x1024, but the scrren
size is 600x1024, IAFW draw logo framebuffer centered, not scrren
centered, so we need this 4-pixels shift workaround to make sure
linux draw logo at the same posotion with IAFW.
This workaround just for demo, should be removed when IAFW fix the issue
