Input: elantech - add Fujitsu Lifebook E546/E557 to force crc_enabled

commit 47eb0c8b upstream.

The Lifebook E546 and E557 touchpad were also not functioning and
worked after running:

        echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add them to the list of machines that need this workaround.
