thunderbolt: Add support for Intel Titan Ridge

Hi,

This series adds support for Intel Titan Ridge Thunderbolt controller. Titan Ridge is the next generation Thunderbolt 3 controller and successor of Alpine Ridge.

In addition to fixes and Titan Ridge support this series adds following:

- USB only security level (SL4).

- A new attribute for devices telling whether they were connected automatically during boot.

- Preboot ACL allows userspace to specify a list of devices (based on device unique_id) that the firmware automatically connects during boot.

The previous versions of the patch series can be seen here:

v2: https://lwn.net/Articles/748030/
v1: https://www.spinics.net/lists/kernel/msg2721243.html

Changes from v2:

- Change wording of the message when Thunderbolt device is rejected by the firmware to be more clear what the reason for the rejection might be. Patches [7/18 and 18/18].
- Use GENMASK() also in ICM_AR_INFO_SLEVEL_MASK in patch [18/18].
- Added Andy's tag to patch [18/18].

Changes from v1:

- Add stable tag to patch [6/18].
- Use tb_xdomain_get() instead of open coding it in patch [12/18].
- If ->get_boot_acl() fails unlock and goto out immediately (follow more

    standard pattern) in patch [12/18].

- Make newline optional in boot_acl_store() in patch [12/18].
- Update Documentation/admin-guide/thunderbolt.rst to show the new "usbonly" security level in patch [17/18].
- Order DMA ports from 3 to 7 in patch [18/18].
- Use 0xffULL instead in get_parent_route() in patch [18/18].
- Sort Titan Ridge PCI IDs numerically in patch [18/18].
- Use GENMASK() in patch [18/18].
- Added Andy's tag to patches 1-17.
