bsps/imsrt: Make flash config more flexible

Browse Source 
The flash configuration is something very board specific. So move the
file to a board specific location. Beneath that, not all controllers and
configurations need the flash config right at the address 0 of the
flash. For example on the i.MXRT11xx, the config has an offset for some
flash types.
