Bug description:
  [SRU Justification]

  [Impact]

  TigerLake platforms fail to probe thunderbolt controller and leaving an
  error message:

    [    2.069944] input: PS/2 Generic Mouse as 
/devices/platform/i8042/serio1/input/input5
    [   21.772011] thunderbolt: probe of 0000:00:0d.2 failed with error -110

  It also introduces a nearly 20 second idle at boot.

  [Fix]

  Commit 57d8df68eb53 ("thunderbolt: Add support for Intel Tiger Lake")
  recently landed to v5.8-rc1 addressed this issue.

  [Test Case]

  Check thunderbolt controller probe messages from dmesg:

    thunderbolt 0000:00:0d.2: 0: unsupported switch device id 0x9a1b
    thunderbolt 0000:00:0d.2: 0: uid crc8 mismatch (expected: 0x8e, got: 0x59)

  [Regression Potential]

  Low. This only enables devices which are previously failed in device
  initialization.
