[RFC PATCH] Input: tm2-touchkey - add hardware dependency

[Jean Delvare <jdelvare@suse.de>]

The tm2-touchkey driver is only useful on specific platforms. Add the
missing hardware dependency so that the driver is not proposed on
systems where the device does not exist.

Note: I am not familar with the hardware in question so I'm not sure
if this is the right dependency to add, or if ARM64 would be more
appropriate, or something else, or a combination thereof. Please
advise.
