Move usb to a graveyard location under sys/legacy/dev, it is intended that the

new USB2 stack will fully replace this for 8.0.

Remove kernel modules, a subsequent commit will update conf/files. Unhook
usbdevs from the build.

+ * To avoid having 1024 TDs for each isochronous transfer we introduce
+ * a virtual frame list.  Every UHCI_VFRAMELIST_COUNT entries in the real
+ * frame list points to a non-active TD.  These, in turn, form the
+ * starts of the virtual frame list.  This also has the advantage that it
+ * simplifies linking in/out of TDs/QHs in the schedule.
+ * Furthermore, initially each of the inactive TDs point to an inactive
+ * QH that forms the start of the interrupt traffic for that slot.
+ * Each of these QHs point to the same QH that is the start of control
+ * traffic.  This QH points at another QH which is the start of the
+ * bulk traffic.
+ *
+ * UHCI_VFRAMELIST_COUNT should be a power of 2 and <= UHCI_FRAMELIST_COUNT.
