A recent commit (see 'fixes' tag) introduced two new elements to each chip family in this table -- except for one: BCM4908. This resulted in the xHCI controller not being initialized correctly, causing a panic on boot. The next patch will update this table to use designated initializers in order to prevent this from happening again. For now, just add back the missing array elements to resolve the regression.
