doc: releases: migration-guide-4.0: document change to USDHC card detect
NXP IMX USDHC fallback card detection method changed from querying the peripheral to simply assuming the card was present. Add a note to the migration guide highlighting this and explaining how to restore the previous behavior for anyone using this detection method.

* The NXP USDHC driver now assumes a card is present if no card detect method
|
||||||
|
is configured, instead of using the peripheral's internal card detect signal
|
||||||
|
to check for card presence. To use the internal card detect signal, the
|
||||||
|
devicetree property ``detect-cd`` should be added to the USDHC node in use.
