ati-vga: Fix aperture sizes
Apparently these should be half the memory region sizes confirmed at least by Radeon FCocde ROM while Rage 128 Pro ROMs don't seem to use these. Linux r100 DRM driver also checks for a bit in HOST_PATH_CNTL so we also add that even though the FCode ROM does not seem to set it.
