video: fbdev: atari: Fix inverse handling
Currently, the "inverse" option does not do anything, as it just sets a flag, which is further unused. Fix this by calling fb_invert_cmaps() instead, like other drivers do. As this only affects the console colormap, this does not affect X. Update the documentation to match the actual behavior.
