On sgi, use CKSEG0 addresses whenever possible for pmap_map_direct and u area
pages. This will allow R5000-based systems with physical memory fitting in CKSEG0 to use 16KB pages and direct maps (since only XKPHYS accesses trigger the XKPHYS coherency errata on these processors). Tested on IP32, IP30 and IP27 (and loongson too as well).
