Devices using the MCUX FlexSPI flash driver erase their flash too slowly, causing the usb stack to freeze, and USB DFU utilities to report a timeout. Enable IMG_ERASE_PROGRESSIVELY for SOCs using the MCUX FlexSPI driver to prevent this error. Fixes #45359 Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>
