atyfb: mark DMI system id table as __initconst 



We can mark the DMI system id table as __initconst by using a helper
variable that'll tell us if we need to unregister the reboot notifier in
atyfb_exit() instead of matching the DMI system id again.

This frees up ~680 bytes of runtime memory, the DMI table occupies.
