drivers/video/au*fb.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
In au1100fb.c, the probe function now returns -ENODEV on failure.
