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.
