When copying the calculation of the stolen memory size for Intels integrated
graphics device of gen 9 and later from the Linux kernel [1], we missed
subtracting 0xf0 from the graphics mode select value for values above 0xf0.
This leads to QEMU reporting a very large size of the graphics stolen memory
area. That's just a waste of memory. Additionally the guest firmware might be
unable to allocate such a large buffer.
