[PATCH] fbdev: prevent drivers that have hardware cursors from calling software cursor code

Browse Source 
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.
