rnoland 4b6831a036 Fix a handful of issues with via agp support.
* Read the pci capability register to identify AGP 3 support
  * Add missing smaller aperture sizes for AGP3 chips.
  * Fix the aperture size calculation on AGP2 chips.
    All sizes between 32M and 256M reported as 256M.
  * Add \n to error string.

This all seems to get the CLE266 EPIA-M board agp working properly, now
back to work on drm.
