Enable Resizable BAR on Unsupported Motherboards

Recently [Rod Burlamaqui] released the arc-rebar project on GitHub , enabling Intel GPUs to work significantly more efficiently if the system’s mainboard does not support resizable BAR. It does require a Debian or Ubuntu installation and of course a supported Intel GPU. Although the resizable base address register (ReBAR) feature has been part of the PCIe specification for a while, its use was quite limited until Intel released its Arc series of graphic cards.
