Tunnels created by boot firmware results in incorrect PCI resource
allocation, which results in failure of extending daisy chain.
This series aligns with windows behaviour of performing a teardown of
tunnels and resetting the downstream ports using DPR during the init
sequence.
Changes since V1:
- Perform DPR only for USB4 routers.
- Update kernel-doc and return value to -EOPNOTSUPP.
- Limit delay range to 10-15ms.

usb4_port_reset()
thunderbolt: Teardown tunnels and reset downstream ports created by
