Testing on MacBookPro12,1 (BTW this is the amazing generation that supports
both USB and SPI, so I'm trying to do something with SPI as well)

1. wasted quite some time trying to "fix" wsp_probe before realizing that it
was probing other things — the actual touchpad interface was occupied by
usbhid!
As a workaround, added a (uaa->info.idVendor == 0x5ac && uaa->info.bIfaceIndex
== 2) check to usbhid_probe.

2. the touchpad's evdev only reports events when moused is running (i.e.
/dev/wsp0 is open)!

3. after just starting moused, there's initially an uhhh stuck finger??
Basically no evdev events for just single finger movement, then adding a second
finger makes one finger show up. Then it usually gets unstuck quickly after
ending the touches (???) and everything starts working properly. At least from
libinput debug-events I can see that 2-3-4 finger gestures get recognized
correctly.
