doc: releases: migration-guide-4.0: document change to USDHC card detect

Browse source 
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.
