显卡添加UEFI支持

UEFI GOP
The UEFI Graphics Output Protocol is a cross-platform abstraction which allows the developer to access graphics output devices. While providing no 3D acceleration and only limited 2D acceleration, the GOP can be used for drawing the GUI of a UEFI application until more advanced drivers are loaded.
