Panel Type Initialization
The VGA BIOS will issue INT 15h function call during POST. This function call
allows the system BIOS to specify the panel type to the VGA BIOS. The system BIOS
should get the panel type from GPIO pins before the VGA chip initialized, and pass
this information to VGA BIOS through INT 15 Function 4E00h.
