Input: ati_remote2 - add missing newlines when printing module parameters

commit 37bd9e803daea816f2dc2c8f6dc264097eb3ebd2 upstream.

When I cat some module parameters by sysfs, it displays as follows. It's
better to add a newline for easy reading.

root@syzkaller:~# cat /sys/module/ati_remote2/parameters/mode_mask
0x1froot@syzkaller:~# cat /sys/module/ati_remote2/parameters/channel_mask
0xffffroot@syzkaller:~#
