[PATCH] fbdev: aty: SPARC64 requires FB_ATY_CT

It looks like SPARC64 requires FB_ATY_CT to build without errors,
so adjust the Kconfig entry of FB_ATY_CT so that it is always 'y'
for SPARC64 && PCI by disabling the prompt for SPARC64 && PCI.

As it currently is, FB_ATY_CT can be disabled, resulting in build
errors:

ERROR: modpost: "aty_postdividers" [drivers/video/fbdev/aty/atyfb.ko] undefined!
ERROR: modpost: "aty_ld_pll_ct" [drivers/video/fbdev/aty/atyfb.ko] undefined!
