[PATCH] au1100fb: Add option to enable/disable the cursor 



- add cursor enable/disable, very useful if you wish a full screen boot
  logo.

Cursor can be disabled from kernel command line:

   video=au1100fb:nocursor,panel:Toppoly_TD035STED4

or from sysfs interface:

   echo 1 > /sys/module/au1100fb/parameters/nocursor

- fix up some wrong indentation issues.
