    Remove incorrect Matrox G200eV support that was previously added by
    commit e3a19388
    
    A serious issue with the incorrect G200eV support that reproduces on the
    Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
    banner, login prompt, etc) on the console when X is not running and
    total lack of text on all of the virtual consoles after X is started.
    
    Any concerns that the incorrect code (upstream since October 2008) has
    been successfully used on non-IBM G200eV equipped system(s) appear to be
    unwarranted.  In addition to the serious/non-intermittent nature of
    issues that have been spotted on IBM systems, complete removal of the
    incorrect code is clearly supported by the following Matrox (Yannick
    Heneault) provided input:
     "It impossible that this patch should have work on a system.
     The patch only declare the G200eV as a regular G200 which is
     not case. Many registers are different, including at least the
     PLL programming sequence. If the G200eV is programmed like a
     regular G200, it will not display anything."
    
    v1 - Initial patch that removed the incorrect code for _all_
         G200eV equipped systems.
    v2 - Darrick Wong provided patch that blacklisted the incorrect
         code on G200eV equipped IBM systems leaving it enabled on
         all G200eV equipped non-IBM systems.
    v3 - Same code changes included with v1 plus additional
         justification for complete removal of the incorrect code.
