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

[ 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.
