QEMU will automatically fill the video BIOS image into memory at the
legacy video BIOS memory location (0xc0000). This code will look
there for a EFI option rom image, and load it if it found. This
allows the video option ROM to be separated out from the main system
firmware image.
QEMU does not appear to emulate the PCI rom expansion method
for making the video BIOS available to the system.

It is not proper for a library implementation to assume the names of function in a parent module.
Instead, they must be designed as the pointers to these two BdsDxe functions and passed in.
