quirks: Add Apple MTP touchpad quirk

Apple M2 (and presumably newer) laptops now embed the touchpad
controller into the main SoC, and use a new internal communications
protocol between it and the main CPU. This isn't really a "bus" like
SPI or I2C, so the downstream kernel driver currently uses the (not
well supported) HOST bus type. MatchBus can't match on that, so let's
just use a name match (plus the vendor ID, which is still valid and
the usual Apple one).
