m68k: atari: Make Atari ROM port I/O write macros return void

The macros implementing Atari ROM port I/O writes do not cast away their
output, unlike similar implementations for other I/O buses.
When they are combined using conditional expressions in the definitions of
outb() and friends, this triggers sparse warnings like:

    drivers/net/appletalk/cops.c:382:17: error: incompatible types in conditional expression (different base types):
    drivers/net/appletalk/cops.c:382:17:    unsigned char
    drivers/net/appletalk/cops.c:382:17:    void

Fix this by adding casts to "void".
