au1100fb fb_blank

Hello,

since some boards need to manage GPIOs to turn on and off the LCD and since on shutdwon the driver does:

   #if !defined(CONFIG_FRAMEBUFFER_CONSOLE) && defined(CONFIG_LOGO)
           au1100fb_fb_blank(VESA_POWERDOWN, &fbdev->info);
   #endif
           fbdev->regs->lcd_control &= ~LCD_CONTROL_GO;

I suggest the attached patch to do the same during boot.

Note that this prevents boards support developers to add specific code before the command:

   fbdev->regs->lcd_control |= LCD_CONTROL_GO;

but putting all these stuff into proper function au1100fb_fb_blank().

Please, let me know what do you think about it.

Ciao,

Rodolfo
