PATCH 1/1 au1100fb.c cursor enable/disable

Hello,

here a patch to 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

The patch also fixes up some wrong indentation issues.

Ciao,

Rodolfo

I'm getting rejects with this patch and with the startup patch. I'm manually fixing it but please check if its okay.
