video: fbdev: atari: Simplify atafb_pan_display()
The fb_pan_display() function in the core already takes care of
validating the panning parameters before calling the driver's
.fb_pan_display() callback, and of updating the panning state
afterwards, so there is no need to repeat that in the driver.
Remove the duplicate code.
