    drm/xe/uapi: Add IP version and stepping to GT list query
    
    For modern platforms (MTL and later), both kernel and userspace drivers
    are expected to apply GT programming and workarounds based on the IP
    version and stepping self-reported by the GT hardware via the GMD_ID
    registers.  Since userspace drivers can't access these registers
    directly, pass along the version and stepping information via the GT
    list query.  Note that the new query fields will remain 0's when running
    on pre-GMD_ID platforms.  Userspace is expected to continue using PCI
    devid / revid on those older platforms.
    
    Although the hardware also has a GMD_ID register for display
    version/stepping, that value is intentionally *not* included anywhere in
    the Xe uapi.  Display userspace should be using platform-agnostic APIs
    and auto-detecting platform capabilities rather than matching specific
    IP versions.
    
    v2:
     - s/revid/rev/  (Lucas)
     - Fix kerneldoc copy/paste mistakes
