[Impact]

New hardware support for Intel Thunderbolt4/USB4 controller codenamed Maple
Ridge, PCI ID 8086:1137.

[Fix]

Patchset titled "thunderbolt: USB4 NVM upgrade improvements & Maple
Ridge support" in
https://<email address hidden>/
currently landed in thunderbolt tree as commit 45ef561abcdd
("thunderbolt: Move max_boot_acl field to correct place in struct icm")
targeting v5.11, as well as commit 62233f88fda2 ("xhci-pci: Allow host
runtime PM as default for Intel Maple Ridge xHCI") from the xHCI tree
also targeting v5.11.

[Test Case]

1. attach thunderbolt docking to the port connecting to a Maple Ridge
controller,
2. use `boltctl list` to enumerate thunderbolt devices connected

[Where problems could occur]

These changes introduce a proxy for USB4 route operations with fallback
to native one depending on the protocol version, so it doesn't seem to
affect exsiting devices.
