video: fbdev: atari: Atari 2 bpp (STe) palette bugfix
The code to set the shifter STe palette registers has a long
standing operator precedence bug, manifesting as colors set
on a 2 bits per pixel frame buffer coming up with a distinctive
blue tint.
Add parentheses around the calculation of the per-color palette
data before shifting those into their respective bit field position.
This bug goes back a long way (2.4 days at the very least) so there
won't be a Fixes: tag.
Tested on ARAnyM as well on Falcon030 hardware.
