Enables the MCUX flash shim driver.

WARNING: This driver will disable the system interrupts for
|
|
the duration of the flash erase/write operations. This will

have an impact on the overall system performance - whether

this is acceptable or not will depend on the use case.

Do a margin check flash command before reading an area.

This feature prevents erroneous/forbidden reading. Some ECC enabled
