    Disable HW cursor by default on G200 server chips
    
    Disable HW cursor by default on G200 server chips as these chips a
    re often used with a remote graphics link which cannot display
    the HW cursor.
    This can be overridden by a config option.
    Most desktops today use ARGB cursors anyhow which are not
    supported by this driver anyhow. Thus the performance penalty
    should be irrelevant.

    Restructure code to make it more readable
    
    With the previous structure it wasn't immediately clear when SecondCrtc
    and HWCursor were set to which value. Make the code more readable.
