[PATCH] fbdev: monitor detection fixes 

From: James Simmons <jsimmons@infradead.org>,
      Kronos <kronos@kronoz.cjb.net>

Various fixes and enhancements to the monitor hardware detection code.  The
only driver that uses it is the radeon driver.

Old EDID parsing code was very verbose, half of the patch address this (ie.
print lots of stuff iff DEBUG).  The other big change is the FB_MODE_IS_*
stuff: we really need a way to know the origin of a video mode.  In this way
we can select video mode that comes from EDID instead of VESA or GTF.

Drivers other than radeonfb won't be affected because they cannot (yet) get
EDID from the monitor and don't use EDID related code.
