fbdev: remove obsolete CONFIG_FB_SOFT_CURSOR

The config Option FB_SOFT_BUFFER was removed in
c465e05a03209651078b95686158648fd7ed84c5 ("fbcon/fbdev: Move softcursor
out of fbdev to fbcon").

While moving to fbcon this single driver has it left as a select in
KConfig / #ifdef in source.  This last occurence is removed here so the
option is really gone
