[PATCH] Assorted matroxfb fixes

[PATCH] Assorted matroxfb fixes

This small change does:

(1) Properly document 'outputs' option.

(2) Properly use accelerated characters drawing.  fbcon used depth == 0
    for character painting long ago, but it is fixed for several months.

(3) Provide correct hints for fbcon about matroxfb/matroxfb_crtc2
    hardware capabilities.
