[new uImage] Add dual format uImage support framework
This patch adds framework for dual format images. Format detection is added and the bootm controll flow is updated to include cases for new FIT format uImages. When the legacy (image_header based) format is detected appropriate legacy specific handling is invoked. For the new (FIT based) format uImages dual boot framework has a minial support, that will only print out a corresponding debug messages. Implementation of the FIT specific handling will be added in following patches. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
