HID: elo: clear BTN_LEFT mapping
ELO devices have one Button usage in GenDesk field, which makes hid-input map it to BTN_LEFT; that confuses userspace, which then considers the device to be a mouse/touchpad instead of touchscreen. Fix that by unmapping BTN_LEFT and keeping only BTN_TOUCH in place. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
