patch enabling pcigart and making sure cmdbuf goes there

DMA queue hangs only happen when the command buffer is in FB. Turning on
AGP on powerpc leads to lockups with DFS, even when using a PCI gart. 
Therefore, current drm has agp_init disabled. This patch enables PCI
gart in the DDX, and makes sure the cmd buffer goes there.
