spl: fit: add support for post-processing of images
The next stage boot loader image and the selected FDT can be post- processed by board/platform/device-specific code, which can include modifying the size and altering the starting source address before copying these binary blobs to their final destination. This might be desired to do things like strip headers or footers attached to the images before they were packaged into the FIT, or to perform operations such as decryption or authentication. Introduce new configuration option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this feature. If enabled, a platform-specific post-process function must be provided.
