mkimage: fit: spl: Add an optional static offset for external data
When building a FIT with external data (-E), U-Boot proper may require absolute positioning for executing the external firmware. To acheive this use the (-p) switch, which will replace the amended 'data-offset' with 'data-position' indicating the absolute position of external data. It is considered an error if the requested absolute position overlaps with the initial data required for the compact FIT. Signed-off-by: Teddy Reed <teddy.reed@gmail.com>
