Tried SR-IOV on XE driver in 265H, problems in Windows 11 and ubuntu 24.04 guests.

I tried to enable SR-IOV patching https://github.com/intel/mainline-tracking/blob/linux/v6.15/drivers/gpu/drm/xe/xe_pci.c

I created a new
```
static const struct xe_device_desc arl_desc = {
/* .graphics and .media determined via GMD_ID */
.require_force_probe = true,
PLATFORM(METEORLAKE),
.dma_mask_size = 46,
.has_display = true,
.has_sriov = true,
.has_pxp = true,
};

```
Modified
```
INTEL_ARL_IDS(INTEL_VGA_DEVICE, &arl_desc),
```

Due intel in https://www.intel.com/content/www/us/en/support/articles/000093216/graphics/processor-graphics.html Meteor Lake (similar to Arrow Lake) is not supported, but Arrow Lake yes.

It is accepted by qemu, but I cannot remove ErrorCode 43 from Windows11. Also spooffing all host IDs!

i915 in VM Linux crash.
xe in VM Linux reports:

```
xe 0000:00:02.0: [drm] ERROR Hardware reports unknown graphics version 0.0
```

I extracted IntelGOPDriver.efi from my BIOS Update.
Every Windows driver tested bring me to Error 43.
