media: uvcvideo: Add GUID for BGRA/X 8:8:8:8 The Cypress EZUSB FX3 UVC example can be configured to report pixel format "e436eb7e-524f-11ce-9f53-0020af0ba770". 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.
