For HS38, we intend to bypass the frame buffer traffic from IOC port. So the frame
buffer start needs to be inside the IOC aperture base address. That value can't be
arbitrary - it is atleast 4K aligned value and further also needs to be aligned to
the size of aperture. So if the size is 16M it needs to be 16M aligned etc...
