skylake: Increase IGD stolen size to 64MB
The FBC hardware for skylake does not have access to the bios_reserved range so it always assumes 8MB is used and so the kernel will therefore need to avoid using the last 8MB of the stolen window. With the default stolen size of 32MB(-8MB) there is not enough space for FBC to work with a high resolution panel.
