Merge patch series "can: add Transmitter Delay Compensation (TDC) documentation"

Vincent Mailhol <mailhol@kernel.org> says:

TDC was added to the kernel in 2021 but I never took time to update the
documentation. The year is now 2025... As we say: "better late than never"!

The first patch is a small clean up which fixes an incorrect statement
concerning the CAN DLC, the second patch is the real thing and adds the
documentation of how to use the ip tool to configure the TDC.
