fbdev: tcx.c fix mem_map to correct smem_start offset 



403ae52a ("sparc: fix drivers/video/tcx.c warning") changed the
physbase initializing breaking the user-space mmap, e.g. for Xorg
entirely.

Fix fbdev mmap table so the sbus mmap helper work correctly, and
not try to map vastly (physbase) offset memory.
