Input: dlink-dir685-touchkeys - fix a typo in driver name

[ Upstream commit 38347374ae3f1ec4df56dd688bd603a64e79a0ed ]

According to the file name and Kconfig, a 'k' is missing in this driver
name. It should be "dlink-dir685-touchkeys".

Fixes: 131b3de7 ("Input: add D-Link DIR-685 touchkeys driver")
