  bus: ts-nbus: Convert to platform remove callback returning void (2023-11-16 12:43:57 +0100)

----------------------------------------------------------------
This series converts all drivers below drivers/bus to struct
platform_driver::remove_new(). See commit 5c5a7680e67b ("platform:
Provide a remove callback that returns no value") for an extended
explanation and the eventual goal.

After the initial simplification in commit 864acca58000 ("bus: fsl-mc:
Drop if block with always false condition") all conversations are
trivial because the remove callbacks all return zero unconditionally.
