One is part of the PCH (Platform Controller Hub, i.e. the chipset) as usual, and the other is inside the actual CPU block. On all Intel platforms that have the two separate DWC3 controllers, the one inside the CPU handles USB3 and only USB3 traffic, while the PCH version handles USB2 and USB2 alone. The reason for splitting the two busses like this is to allow easy USB3 tunneling over USB4 connections. As USB2 is not tunneled over USB4, it has dedicated USB controllers (both xHCI and DWC3).
