Subject: Catch FreeBSD up to the pcie gart changes. Required minor
modification to radeon_cp.c to use a drm_local_map_t-type mapping
(drm_core_ioremap rather than drm_ioremap), which contains private device
mapping information on BSD. I also changed the ati_pcigart interface to
use "void *" for pointers to kva rather than "unsigned long". While
PCIGART support appears to be broken on FreeBSD currently, I think this
is not new, and BusType PCI remains working on my r100 in Linux.
