This is its GUID for BGRA/X 8:8:8:8. The UVC 1.5 spec [1] only defines GUIDs for YUY2, NV12, M420 and I420. This seems to be an extension documented in the Microsoft Windows Media Format SDK[2]. This Media Format SDK defines this GUID as corresponding to `MEDIASUBTYPE_RGB32`, which is confirmed by [4] as `MEDIASUBTYPE_ARGB32` has different GUID. Note that in my case, the FX3 UVC can output either channel order, BGR or RGB or any other mix for that matter. Since Linux commit 1b8dc32286a1a ("[media] uvcvideo: Add GUID for BGR 8:8:8") defined a GUID for `MEDIASUBTYPE_RGB24` channel order as BGR, keep this change consistent and define `MEDIASUBTYPE_RGB32` as BGR as well. Document [3] also indicates the channel order is BGR.

We can set the format description and compressed flag from v4l_fill_fmtdesc and can remove the extra name field in uvc_format_desc.
