[IA64] agp/hp-agp: Allow binding user memory to the AGP GART 

dmesg reports:
[   29.365973] [TTM] AGP Bind memory failed.

[   29.367030] [drm] Forcing AGP to PCI mode

This patch allows binding user memory to the AGP GART on zx1-based
systems. dmesg thus no more complains about AGP bind memory failure,
disabled GPU acceleration or AGP mode forced to PCI.

Original work from Francisco Jerez in agp/amd-k7
(https://lkml.org/lkml/2010/10/15/469).
