hwdb: add a touchpad hwdb
Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon 3rd. These laptops re-introduced the physical trackpoint buttons that were missing from the *40 series but those buttons are now wired up to the touchpad. The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same button codes were used in older touchpads that had dedicated scroll up/down buttons. Input drivers need to work around this and thus know what they're dealing with. For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but the resulting mess showed that these per-device quirks should really live in userspace. The list currently includes the X1 Carbon 3rd PNPID, others will be added as get to know which PNPID they have.
