The imx USDHC driver previously queried the peripheral's internal card detect signal to check card presence if no card detect method was configured. However, some boards do not route the card detect signal and do not work correctly with the DAT3 detection method supported by this peripheral. As a fallback, assume the card is present in the slot but log a warning to the user. Fixes zephyrproject-rtos#42227 Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>
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.
