thunderbolt: Changes for v6.19 merge window

This includes following USB4/Thunderbolt changes for the v6.19 merge
window:

  - Documentation fixes
  - Fixes for various typos found in the driver
  - Replace use of system_wq with system_percpu_wq.

All these have been in linux-next with no reported issues.

upgraded to the latest where possible bugs in it have been fixed.
Typically OEMs provide this firmware from their support site.
There is also a central site which has links where to download firmware
for some machines:
`Thunderbolt Updates <https://thunderbolttechnology.net/updates>`_
Currently, recommended method of updating firmware is through "fwupd" tool.
It uses LVFS (Linux Vendor Firmware Service) portal by default to get the
latest firmware from hardware vendors and updates connected devices if found
compatible. For details refer to: https://github.com/fwupd/fwupd.
Before you upgrade firmware on a device, host or retimer, please make
sure it is a suitable upgrade. Failing to do that may render the device

Host NVM upgrade on Apple Macs is not supported.
Once the NVM image has been downloaded, you need to plug in a
Thunderbolt device so that the host controller appears. It does not
matter which device is connected (unless you are upgrading NVM on a
device - then you need to connect that particular device).
Fwupd is installed by default. If you don't have it on your system, simply
use your distro package manager to get it.
To see possible updates through fwupd, you need to plug in a Thunderbolt
device so that the host controller appears. It does not matter which
device is connected (unless you are upgrading NVM on a device - then you
need to connect that particular device).
Note an OEM-specific method to power the controller up ("force power") may
be available for your system in which case there is no need to plug in a
Thunderbolt device.
After that we can write the firmware to the non-active parts of the NVM
of the host or device. As an example here is how Intel NUC6i7KYK (Skull
Canyon) Thunderbolt controller NVM is upgraded::
Updating firmware using fwupd is straightforward - refer to official
readme on fwupd github.
If firmware image is written successfully, the device shortly disappears.
Once it comes back, the driver notices it and initiates a full power
cycle. After a while device appears again and this time it should be
fully functional.
Device of interest should display new version under "Current version"
and "Update State: Success" in fwupd's interface.
Upgrading firmware manually
---------------------------------------------------------------
If possible, use fwupd to updated the firmware. However, if your device OEM
has not uploaded the firmware to LVFS, but it is available for download
from their side, you can use method below to directly upgrade the
firmware.
Manual firmware update can be done with 'dd' tool. To update firmware
using this method, you need to write it to the non-active parts of NVM
of the host or device. Example on how to update Intel NUC6i7KYK
(Skull Canyon) Thunderbolt controller NVM::
# dd if=KYK_TBT_FW_0018.bin of=/sys/bus/thunderbolt/devices/0-0/nvm_non_active0/nvmem
