It matches by vendor/device ID just like PCI does, and does the bus
clock management and power management in a really nice way, which I
doubt platform devices will ever do.

The way this discussion is going, I'm going to suggest that we also
convert PCI stuff to being platform devices too.  I don't see the
point of PCI existing for all the same reasons being given in this
thread.
