[PATCH] fbdev: prevent drivers that have hardware cursors from calling software cursor code
This patch removes drivers that have hardware cursors from calling the
software cursor code. Also if the driver sets a no hardware cursor flag
then the driver reports a error it someone attempts to use the cursor.
