HID: elo: clear BTN_LEFT mapping
[ Upstream commit 9abd04af951e5734c9d5cfee9b49790844b734cf ]
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.
