Bugzilla #5766 <https://bugs.freedesktop.org/show_bug.cgi?id=5766> Patch

    #4636 <https://bugs.freedesktop.org/attachment.cgi?id=4636>
- Acknowledge that RN50 only has one CRTC, and use this to distinguish it
    from RV100.
- Fix detection of RN50 memory type and bus width.
- Model RN50 memory bandwidth limits by capping the pixel clock range based
    on memory clock, bpp and memory bus width. (ATI Technologies Inc.)
