Theres nothing PCI specific here. Should this be defined somewhere in
the PCI layers so PCI classes. First thing I had to do for EHCI
equivalent was copy paste this s/UHCI/EHCI with no other change.

Therese three elements (parent, instance_size, class_init) are
repeated from one definition to the next. This will get tedious when
we eventually come to make the same fix for some of the other devices
that have large numbers of variants (pflash_cfi0x and m25p80 being
some of the angrier ones).
