hw/usb/uhci: Declare QOM macros using OBJECT_DECLARE_TYPE()

The automatic conversion done during commit a489d1951c
("Use OBJECT_DECLARE_TYPE when possible") missed this
model because the typedefs are in a different file unit
(hcd-uhci.c) than where the DECLARE_INSTANCE_CHECKER()
is (hcd-uhci.h). Manually convert to OBJECT_DECLARE_TYPE().
